@Augustine_Whitehouse,
Yes, you can add details and trigger record retrieval from retool db when clicking on the waypoints in your mapbox component. First, have you mapped your waypoints from your retoolDB to the mapboxMap component along with your point ids?
If so, you can then add a resource query to your retoolDB that runs "on point select". This query will reference the {{name_of_mapboxMap_component.selectedPoint}} property, which will include the point id in your database.
Let me know if you need help with it. (don't listen to your partner!)
