javascript - React Native How To Convert Route to Navigation State

Question

I am trying to implement react navigation v5's deep linking system to my react native app. So far its working but I am started get confused. So my aim is make initial screen to get params while navigating to specified screen. I can explain it better with code:

const config = {
screens: {
    HomeStack: {
        screens: {
            Home: {
                screens: {
                    SearchStack: {
                        initialRouteName: 'Search',
                        screens: {
                            PostDetailStack: {
                                initialRouteName: 'PostDetail',
                                screens: {
                                    PostDetail: 'post-detail/:postId',
                                    CommentDetail: 'post-detail/:postId/:comment/:commentId'
                                } 
                            }
                        }
                    }
                }
            } 
        }
    },
    AuthStack: {
        screens: {
            ChangePassword: 'reset/:uid/:token'
        }
    }
}
}

So while navigating to CommentDetail screen I also want to pass params to PostDetail screen. In react navigation docs it says I need to use getStateFromPath(path, config) to copy params but I don't know how to use that. I tried to convert this route to state but I got confused and I also don't get when we use index in navigation state and when we don't. So how can I convert this to proper navigation state that initial screen also gets the params?
