New Multipurpose Sensor- where is vibration option?

Newbie to smarthings…

I just bought a bunch of these new multi-purpose sensors. I’ve installed my first one and either I installed it incorrectly, or there is something else I have to do to see the “vibration” option? I see status, temperture…nothing about vibe. How would I ask to be notified if someone knocked on the door?

You should see a “Active” or “Inactive” tile. This is the indication of vibration.

ahhh. I do see that! I didn’t understand that, I just thought the sensor was online=active! Ok, can you point me to a tutorial or give a tip how to use that to notify me of a knock?
