php - Unable to override function in WordPress child theme

Question

I am currently working on a website using WordPress and the ColorMag theme and I'd like to modify the basic theme using a child theme (Child Theme Modificator).

What I need to modify is the colormag_below_header_bar_display (line 478) function by adding a language toggle like this:

if ( ! function_exists( 'colormag_below_header_bar_display' ) ) :

    /**
     * Function to display the middle header bar.
     *
     * @since ColorMag 1.2.2
     */
    function colormag_below_header_bar_display() {

        $random_post_icon = get_theme_mod( 'colormag_random_post_in_menu', 0 );
        $search_icon      = get_theme_mod( 'colormag_search_icon_in_menu', 0 );
        ?>

        <nav id="site-navigation" class="main-navigation clearfix" role="navigation">
            <div class="inner-wrap clearfix">
                <?php
                if ( 1 == get_theme_mod( 'colormag_home_icon_display', 0 ) ) {
                    $home_icon_class = 'home-icon';
                    if ( is_front_page() ) {
                        $home_icon_class = 'home-icon front_page_on';
                    }
                    ?>

                    <div class="<?php echo esc_attr( $home_icon_class ); ?>">
                        <a href="<?php echo esc_url( home_url( '/' ) ); ?>"
                           title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>"
                        >
                            <i class="fa fa-home"></i>
                        </a>
                    </div>
                <?php } ?>

                <?php if ( 1 == $random_post_icon || 1 == $search_icon ) { ?>
                    <div class="search-random-icons-container">
                        <?php
                        // Displays the random post.
                        if ( 1 == $random_post_icon ) {
                            colormag_random_post();
                        }

                        // Displays the search icon.
                        if ( 1 == $search_icon ) {
                            ?>
                            <div class="top-search-wrap">
                                <i class="fa fa-search search-top"></i>
                                <div class="search-form-top">
                                    <?php get_search_form(); ?>
                                </div>
                            </div>
                            <?php pll_the_languages(array('show_flags' => 1, 'show_names' => 1, 'hide_current' => 1 ) ); ?>
                        <?php } ?>
                    </div>
                <?php } ?>

                <p class="menu-toggle"></p>
                <?php
                if ( has_nav_menu( 'primary' ) ) {
                    wp_nav_menu(
                        array(
                            'theme_location'  => 'primary',
                            'container_class' => 'menu-primary-container',
                            'items_wrap'      => '<ul id="%1$s" class="%2$s">%3$s</ul>',
                        )
                    );
                } else {
                    wp_page_menu();
                }
                ?>

            </div>
        </nav>

        <?php

    }

endif;

The part that I added is: <?php pll_the_languages(array('show_flags' => 1, 'show_names' => 1, 'hide_current' => 1 ) ); ?>, which is a function steming from the Polylang plugin.

When editing this file in the normal theme, everything works and the language switcher is visible in the right part of the navigation bar - however it is not visible on the child theme.

When I try to do this via the Child Theme Modificator plugin, the file that the function is located in (inc/template-tags.php), is not selectable as a file to transfer to the child theme:

Manually copying the modified version into the child theme via FTP did not work either. The modified version of my function does not seem to be used in that case.

I am quite new to WordPress/PHP and the creation of child themes, so any help would be greatly appreciated.
