No response of UI after webgl full screen on Android

I'm using full screen webgl on Android.

The UI of unity 2019.4.17 can respond normally, but after updating to unity 2020.1, the UI cannot respond to touch after full screen. So I'm going to unite 2020 com.unity.ugu Replace with ugui of unity 2019, and the UI can respond to touch normally.

However, after upgrading to untiy2020.2, ugui has changed greatly and cannot be replaced with 2019 ugui.

Full screen JS code under webgl: function SetFullScreen() { if ( document.fullscreenElement Wei document.webkitFullscreenElement Wei document.mozFullScreenElement Wei document.msFullscreenElement ) return;

var element = document.documentElement ; if ( element.requestFullscreen { element.requestFullscreen (); } else if ( element.mozRequestFullScreen { element.mozRequestFullScreen (); } else if ( element.webkitRequestFullscreen { element.webkitRequestFullscreen (); } else if ( element.msRequestFullscreen { element.msRequestFullscreen (); } }
