1. What is the issue? Please be detailed.
I would like to query ArcGIS layers using Entities in my workflow. This would be a point-in-polygon query. So the user clicks on a map, then a query is made to an ArcGIS layer to get a specific value and populate a field in my form. I could not find examples using ODK, but I came across this workflow supported by Survey123 using pulldata() - https://community.esri.com/t5/arcgis-survey123-blog/survey123-tricks-of-the-trade-pulldata-quot-layer/ba-p/1224415
2. What steps can we take to reproduce this issue?
Please have a look at the following demonstration implemented using Survey123
The above link show cases the following workflows:
Point-in-polygon calculations using a map - the user click on a map to get the coordinates.
https://community.esri.com/t5/image/serverpage/image-id/54164i31AD912483FBDACB?v=v2
Point-in-polygon calculations using an address - the user types an address which is then geocoded to get the coordinates

Point-in-polygon queries for data validation
https://community.esri.com/t5/image/serverpage/image-id/54171iDC30151DC9D6900E?v=v2
Can a workflow like this be supported by Collect and Enketo (maybe the new webform engine)
3. What have you tried to fix the issue?
What I thought of is to take the geopoint (Latitude & Longitude) and ingest these into the ArcGIS layer rest end point:
https://services.arcgis.com/P3ePLMYs2RVChkJx/ArcGIS/rest/services/World_Administrative_Divisions/FeatureServer/0/query?where=1%3D1&objectIds=&geometry=148.176%2C-37.491&geometryType=esriGeometryPoint&inSR=4326&spatialRel=esriSpatialRelWithin&outFields=*&returnGeometry=true&returnIdsOnly=false&f=json
From the URL above I would replace geometry=148.176%2C-37.491 with geometry=${latitude}%2C${longitude}
But I am stuck on how to accomplish this.
I am also stuck on how to grab the the relevant value from the json output and ingest in the country field
