What are Layout templates? https://support.google.com/meethardware/answer/9295022?hl=en
a) Auto - Allow application to choose the layout for you.
b) Tiled - When there is no presentation, this layout shows a grid view of equal-sized images. When there is a presentation, the presentation is shown in a larger format with speakers shown alongside it.
c) Spotlight - Full-screen layout with the option to display the presentation, active speaker, or participant you pin. When you pin a participant or presentation, they’re always visible.
d) Sidebar - One main image of a participant or the presentation. The images of other meeting participants are on the side.
Today saw a Google Meet with about 100 participants in 8x6 tile view (some of the participants weren't shown in the tile view) so one of the tiles had something like +53 more participants. Please ensure that when all the participants do not fit on the screen in tile view there is a tile with the additional participants.
Not sure what happens as there is 3 pages of participants; however, it seems that clicking on +53 more participants would show the next page of participants. Or maybe a tile page should be added when there are more participants that can fit on one tile view.
