In ArcMap, there was this very useful join based on spatial location.

This enable you to count how many entities, e.g. buildings within each polygon of your input polygon layer, e.g. city boundaries. So you could know how many buildings there were in each city.
I can't find any functionality in Pro enabling one to do this.
Am I missing something ???
