Why is "Meet Attendance" icon not enabled in Google Meet?

I (seem to) have installed the [Meet Attendance](https://chrome.google.com/webstore/detail/meet-attendance/nenibigflkdikhamlnekfppbganmojlg?hl=en) Chrome extension for Google Meet by claycodes.org from Chrome Web store from my Android phone. The site responded by messaging that it has been _added to the desktop_. But I find that the feature is not enabled when I start Google Meet on my Android phone, because I can not see the *checkbox icon* representing "Meet Attendance" during the Google Meet session. Can I have this feature enabled so that I can use it on my Android phone?
