As a new ArcGIS Pro user, it seems like I should be able to use the Explore tool to get/copy the mouse pointer's current coordinates — at a position in the map that doesn't have features.
In other words, identify on a blank map or on the basemap to get the coordinates.

There are likely several different ways to get the coordinates of the mouse pointer. But as mentioned, as a new user, it seems unintuitive that I can't do it this specific way.
