Note: The meeting host can disable attendee annotation. If you do not have the annotation option, confirm that the host has not disabled annotation.
If you have any more specific details about the show or your preferred method of watching, I could try to provide a more tailored response.
Zoom’s in-meeting product features allow you to add annotations on your screen during your video calls — a tool for remote teams to easily brainstorm and collaborate. Meeting participants can add annotations while screen sharing as a viewer or the one that started sharing their screen. You can also use annotation tools when sharing or viewing a whiteboard.
