I'm piggybacking off a post by @Adam_Bourque here as I recently noticed myself that the right click "What's here?" functionality in Map Viewer does not pull through into Experience Builder and as far as I can tell it cannot be enabled in the settings. I couldn't see another idea asking for this so here I am.
I'm aware we can add the coordinates widget to our app but this right click functionality is simpler and matches the similar function you see in Google Maps.
If this could be implemented I think it would be a great addition.
Thanks
Anthony
