How to access document or dom element from WebAssembly (blazor)

Question

In my minimal blazor app there is this razor file:

@inherits LayoutComponentBase
@using Microsoft.JSInterop
@inject IJSRuntime JS;

<div class="page">
    <div class="main">
        <canvas width="200px" height="200px" @onclick="Test" style="background-color:aquamarine" />
    </div>
</div>

@code {
    private void Test()
    {
        try
        {
            var window = WebAssembly.Runtime.GetGlobalObject();
            WebAssembly.JSObject jso = WebAssembly.Runtime.GetGlobalObject("document") as WebAssembly.JSObject;
        }
        catch (Exception ex)
        {
            string dbg = ex.Message;
        }
    }
}

When I click on the canvas, I get this exception:

assembly:<unknown assembly> type:<unknown type> member:(null)

What am I missing?

Thanks!
