Why I do not use the webview2 prompts for permissions (wv2 136 lastest) :

[jls28]

Sometimes webview2 prompt for a permission but this is not reliable :

Firstly, for notifications, it never prompt (a bug probably). The permission is denied but no webview2 permission is defined.

Otherwise, from my tests, I see than if the prompt for a permission is closed three times with the close button, this stop permanently the display of this prompt (error below),
the only way I know to restore the prompt is to use a new profile or clear the user profile;

So my advice is to never use the webview2 prompt for permissions, because if the user
close the prompt three times with the close button, the prompt disappear definitivly for this user profile.

I discovered there are an chrome option "--disable-features=BlockPromptsIfDismissedOften"
so I tried and this change (unfortunately) nothing.
