After I had it installed I found Annotate Meet easy to use. There is one quirk to be aware of before you start using it. The default color for the drawing tool is black which might not show up all that well depending upon the screen you're sharing. For example, if you screenshare a Google Document the black pen tool might not be enough of a differentiation from the text for your students to notice right away. I changed the color to a darkish orange color and the pen tool was much easier to see.
Applications for Education
Annotate Meet could be useful for providing remote tech support to students. I would use the annotation tool to draw on my screen to show students where they to click on their own screens. Annotate Meet could also be great for drawing on articles to highlight important parts of articles that you share with your students. I'd also consider using it when providing remote editing or feedback to students.
I probably wouldn't use Annotate Meet if I was conducting a full lesson that required drawings and diagrams. Those kinds of lessons I prefer to do a shared Google Jamboard because I can quickly provide students with a copy of Jamboard via Google Classroom whereas annotations on a screen in Google Meet aren't available to students after the meeting ends.
