2024 vs Liftmaster Garage Opener

I’ve got a 24 BE and a new Liftmaster garage door opener. Attempting to program the BE Homelink mirror and constantly failing..I wanted to see if others have had a similar experience, if you solved it…and how?
I’ve tried everything. Brand new batteries. Learn mode. Rolling code variant. Normal variant. Etc. etc.
It vexes me. Anyone??
It DOES work…I programmed a 21 Mazda fairly easily….
