[fahrulseptiana]

Hi, i had to say thank you for this amazing browser apps.

Since I had so many activity on web browser on android, I found out that this browser need more basic API support nowadays. I would like to say thanks if current devs can add more API support.

We can find out the example test here for Clipboard API https://googlechrome.github.io/samples/async-clipboard/

For the implementation I had find it's permission is separated from PermissionRequest (which is work for requesting camera and microphone access from webview), you can check here https://stackoverflow.com/questions/61243646/clipboard-api-call-throws-notallowederror-without-invoking-onpermissionrequest
