Publisher permissions WebCam and Mic

I wanted to know if there’s any way that the prompt of asking for permissions for the camera and microphone doesn’t show up and has these functions directly blocked?

You have full control of the application using OpenVidu browser SDK. So you can add or remove any button in the graphical user interface to block user to publish.

Also, you can use SUBSCRIBER role when generates token. So the participant can not publish in the session.
