I am trying to connect external fingerprint scanner to the Android application which is in Kiosk mode(Android COSU). A system dialog should be displayed to ask for the permissions in order to access the fingerprint scanner. However, In kiosk mode, I cannot see any System dialogs showing up. Is there a way where I can display system dialogs in Kiosk mode?
Edit: I am able to access Runtime permission dialogs but not Finer print authentication dialog. So, I guess there is some issue only with the USB permission dialog.
