summary of related table in unbinned point layer

[clt_cabq]

I have a point layer of address locations, and a related table of police and fire calls that have gone to each location. For each point/address I'd like to provide a summary of the call types (distinct call types, count) in my pop up. Looks like I could do this using arcade for a layer that has been aggregated but unclear that I can get there via a related table and point layer. Any suggestions?

What you're asking for sounds a bit like this example.   Summarize intersecting points in a popup | Sample Code | ArcGIS Maps SDK for JavaScript 4.26 | ArcGI...

I think I had gone down that rabbit hole a little or another example very similar to that, my issue is I don't have a polygon to intersect against and the data are in a related so in some respects are aspatial. I could so something along those lines using a parcel layer, not sure that is the right approach, partly as it will add overhead to the map I think at some level.
