New method to open / close Chamberlain MyQ garage door

I gave up on this method to open my garage door. The MyQ code kept changing. I went with a Zooz relay. Works 100% of the time.

How to wire zooZ Zen16 to garage door opener

I think I just don't quite understand how the Zen16 works. Maybe the garage door opener as well. It seems to me, that pushing the wall button just sends a signal (by way of completing a circuit so voltage is detected?) to the ceiling unit telling it to open/close. The Zen16 is just a relay. So if I wire the switch to the Zen16 and the Zen16 to the GDO... how does it actually work? I'm guessing... the relay in the Zen16 stays open. When it detects voltage from the switch, it closes the relay mom…
