It appears that Grid View for Google Meet is a Chrome extension. Please note that Chrome extensions are not compatible with Android versions of Chrome or Chromium and our Elements series panels, ActivConnect-G, and OPS units are running Android.
To get grid view to work on Android, you may want to reach out to Google and see if they have any suggestions.
You can also connect your computer to your panel via HDMI to display what shows on your computer to the panel. That way you can use Grid view on your computer and show it on the panel.
Please let us know if we can answer anything else for you.
