Unable to record specific screens during local recording

[kei41]

In a meeting with multiple participants, I joined using a guest account. One user is sharing their screen, and I want to record only that person.

Last time, I pinned the user to keep them fixed and recorded.
When screen sharing started, I switched screens using the top tabs to ensure the speaker remained visible.
However, when reviewing the recording, it switched to recording the shared screen the moment screen sharing began.

Please advise if there's a way to keep only the speaking user fixed and recorded even when screen sharing occurs.
