In a Google Meet, whoever is speaking is front & center on the screen.  When there is a large number of students or staff in the Google Meet, the Google Meet screen will keep switching who is front & center.  If you need to focus on one particular person, for example, students may want to make sure the teacher is front & center on the screen, you can use the Google Meet pinning feature.
