I am making website in wordpress but it is not asking permission for mic and camera

It is not asking any permission what to do
Please tell me procedure to ask permission to user of mic and camera. As mic and camrea are not starting and it says permission not granted

I have found this issue from time to time, for me the answer is to select the small video camera icon in the right hand side of the web browser’s address bar, and then allow the web page to access the camera and microphone. I hope this solves your issue too.
