With the current online meeting style, attendees can take screenshot of what is being presented and this might be a big breach in the case where the content being shared is highly sensitive. With the recently released Teams Premium, you have the capability to publish sensitivity labels that will assist you in easily identifying the person that captured the screenshot.
When you join a meeting that is protected with this sensitivity label and encryption, you will get a water mark that contains your email address( user@company.com) on the presentation and video feeds from the attendees. This means that even when someone take a screenshot it can be traced back to the originator because of the watermark that contains the identifaable details(UPN) below.
