Nothing can be changed on a company Mac

Managed Macs have their permissions set by IT. The switch is then not merely off but locked, and no guide will move it — that is deliberate rather than broken. The only way through is a request to IT, and it goes faster when it is specific.

Ask IT for a configuration profile granting the meeting application screen recording and — if remote control is needed — accessibility. The application identifier is on its guide page, beside the Terminal command; that is exactly what IT needs.
