[FEATURE] Show Message to user when they deny permissions

[digitallysavvy]

Is your feature request related to a problem? Please describe.
Currently when a user joins a channel they are prompted with camera permissions. In some instances the user may deny camera/mic permissions. This causes the stream init to fail. The user is still added to the RTM channel so the other users can see a user in the channel but there is no video/audio added to the channel. This gives off the impression that there is an error with the video chat even though it is human error causing the issue.

Describe the solution you'd like
Can there be a message on the screen to alert the user that their video and audio are not visible because they did not give permission. Can there be a prompt for the user to enable their camera/mic permissions?

Also need to show a message to remote users that Guest/"XXX" user has joined the channel without their video/audio enabled.
