Technical explanation
The Permissions API exposes some permission states by name. Support varies by browser and permission. Camera and microphone states may be hidden until the page has requested them at least once.
A prompt state means the browser has not decided yet. The page cannot grant permission on your behalf and cannot bypass a blocked state.
Troubleshooting
States show unsupported
The browser may not implement Permissions.query for that name.
Camera still shows prompt after granting
Some browsers do not expose media permission state until a stream is opened.
A permission is blocked
Use the browser site settings to reset it.
Location is not available
Check system location services and the secure-context requirement.
