Webview 2 . How do I export my game without borders and windows navigation?

After the export, when I'm running my game I see that it is not fullscreen. I see that it is running in the window mode, on the top side I see Windows navigation on the bottom side I see Windows panel. Is it possible somehow to run the game in real fullscreen mode?

The WebView2 export option supports fullscreen mode if you use the Browser object's 'Request fullscreen' action.

thank you very much. I will try

The browser plugin actions include requesting and canceling a fullscreen.

Yes. this was the issue. I checked the code and I added the browser fullscreen but it doesn't work on game start. It works only if add 1s timeout in my case. I don't know if it is valid for me only, maybe I'm doing something wrong, but anyway, it works now. Thank you guys for help
