What are the two walnut-sized "bumps" on the top of my rearview mirror?

Dear Forum, I seem to be a repository for dumb, inane questions. Here's my latest: The rearview mirror on my 2019 Grand Caravan GT has two walnut shaped bumps on top of it and for the life of me, I can't figure out what they are or for. Any more knowledgeable forum members out there that can enlighten me? Thanks. Frank the Van Guy
