I'm hosting a feature on AGOl, and brought it into my Enterprise Portal as a feature service.
In portal, I have a map, utilized by Field Maps, that has the abovementioned feature service in it.
I created a Power Automate flow that sends an email any time a new feature is added. Within that email, I'd like to include a hyperlink that launches the specific map in the Field maps app, and zooms to the location of the newly added feature.
I'm able to create a link that successfully launches the correct map in the Field Maps app, but hit a road block when trying to access a specific feature.
I can get the URL to return the GlobalID; however, can't seem to figure out the featureSourceURL part.
In Portal, the web service rest URL returns this, so I can't obtain the typical rest URL:

If I enter the rest URL from AGOL, I get an error when Field Maps launches advising that layer cannot be found (since the layer isn't being added to the map directly from AGOL.)
