Hi, Michael.
To use this feature you must grant camera permissions to PowerPoint in your computer's privacy settings and run Beta Channel Version 2202 (Build 14922.10000) or later. If you meet these requirements, try updating Office and see if the feature becomes available to you.
Click File → Account → Update Options → Update Now.
If the feature is still not available you will need to wait. As the feature became available in February, it is slowly rolling out to insiders.
