I am really new in ArcGIS Online and first steps in coding.

I created a webmapp app: users can create clinics (as points) and each time they create a new point they have to choose in a list the region, the province and the district (attributes editing in a pop up) I added to the webmap a district layer (as polygons) with 3 fields (region name, province name and district name)

I would like each time they create/edit a new clinic, the mentioned fields are automatically populated with the values of the district the clinic is within. I searched quite a lot, and i dont really know how to calculate a field on the fly or what would be the expression and the language for it. I think it should be on the pop config with SQL but i really don't know where to start.

Do I do that in the webmap, with another tool in ArcGIS Pro or using ArcPy?
