I built an advanced app clip experience, associated it to a location, and its MATCHED. The status is marked (green) RECEIVED. However, I am unable to see the invocation on Maps. I don't see the buttons such as SUPPORT/ORDER shown for that place. The docs does not explain why. What is the exact requirement for us to surface buttons for POI? We are authorized by the businesses to add these for them. I'd love to hear in detail the exact process to add buttons for POI - how Uber Eats and Door Dash does it for restaurants and how their app clips get shown. Thank you.
