Wouldn't it be great if could add the List Action > When selection changes > Show Pop Up for a Map Image Layer data type? This functionality is only available for the Feature Layer data type. Currently, you have to manually select a feature in the map for the Pop Up to open.
This would be nice for when Feature Access is not enabled on data for various reasons. We are using Map Image Layers within Web Maps, Dashboards, and Experience Builders and would like the ability for Pop Ups to be an Action. This functionality is more straightforward to the users rather than users having to manually select a feature to see the Pop Up. Since Pop Up are a function for Map Image Layers in Web Maps, it should be an Action in Dashboards as well.
