WebViewer security police error


I am loading an HTML file that uses an MIDI usb devices library, when loading on google chrome its ask for permissions to use USB Midi but when i load in Kodular WebView it gives the error below:
I have tried ask permissions in app launch but i dont know whats the midi android permission i should ask.
By the way the library i am using its called WebMidi.

Try the custom webviewer extension


Thanks i managed to make it work with Custom WebView, but only when i disabled the PromptForPermission.

Please provide a screenshot of your working solution
