Niro EV Mystery buttons

[abrasiveMARCH]

Okay, so I'm a total newbie to the Niro EV. Just picked up a 2023 Wave and I'm stumped by these three buttons under the rearview mirror. What do they do? Anyone know what they're for? I'm guessing garage door opener, but the manual is as helpful as a chocolate teapot.

You're right, that's the HomeLink system. You can find online videos explaining how to set it up.
