Description

When using the electron app, if I add blocks to record from the recording extension, it only runs for a very brief amount of time and doesn't actually seem to record anything. I'm guessing it might be a permissions issue with the computer mic?

Research direction

Start by reproducing the failure in the Electron app with the linked test project and the recording extension, then inspect the recording and microphone-permission entry points. Done means recording blocks run for their expected duration and capture audio in the simulator; verify behavior with the relevant computer microphone permissions enabled and disabled.
