hey @abirc8010 ,I believe that prompting the user to grant permissions might provide a better user experience. By proactively guiding users to enable the necessary permissions, we can prevent confusion and make the process more seamless. Instead of just showing an error message, prompting users to grant permissions directly can help ensure they understand the action needed to proceed.

your thoughts @Spiral-Memory ?

@smritidoneria
You are right !
Let's prompt user to enable the permission and then we can start the recording
