I have a database with points data. Each has a group and points in a group represent a boundary (polygon) on the map. I am trying to use these boundaries with Geotriggers to alert the users when they move in and out of boundaries. I have used the location driven Geotriggers sample from git hub to get an idea on how to achieve this . https://github.com/Esri/arcgis-runtime-samples-android/tree/main/kotlin/set-up-location-driven-geotriggers  The only difference is that the sample uses portal items and the data I have is a set of points. So instead of using portal items I create a feature collection with polygon table with a single geometry in the shape of a square. On running the application I do not see alerts at all when the simulated location source moves in and out of the boundary. I have included the code below so it is easier to understand what I am doing. Is it possible to implement this feature with polygon feature tables? Are we able to use Geotriggers without showing a map to the user? package uk.co.deloitte.foregroundservice; import androidx.annotation.NonNull; import androidx.appcompat.app.AppCompatActivity; import androidx.core.app.ActivityCompat;
