Displaying your screen content to others during a Teams meeting or call
Based on my research, currently I cannot find any officially documentation of a setting in Teams for Web (Chrome on macOS) that allows the meeting gallery, participant list, or self-view to remain visible while you are viewing the shared content in the same browser window. The available information for browser-based screen sharing does not describe such an option.
If you are presenting a PowerPoint file, you may wish to explore PowerPoint Live, which offers a presenter-focused experience for PowerPoint presentations. However, this is specific to PowerPoint content and may not address the broader scenario of viewing participants while sharing an entire screen, application window, or browser tab
I hope this helps. If you have any additional questions, please feel free to reply.
