In Entra ID, there are certain applications listed under Enterprise Apps that aren't Microsoft defaults, but they only appear when the "Enterprise Applications" filter is disabled. Why do these applications not show up when filtering for "Enterprise Applications"? For example, the Foxit PDF Helper is one such app.

The reason those apps don't appear is that there's no actual concept of an enterprise app at the API level—it's more like a view Microsoft provides. The things you see filtered out are service principals that lack a management structure around them in that view, such as managed service principals. For a deeper explanation, check out this link.

I read that link after you posted it, and it clarified a lot! But I'm still curious about how Microsoft decides which service principals are included in the "enterprise apps" filter. At first, I thought it might mean all non-Microsoft apps, but that doesn't seem to apply in my case. Can someone break down what 'additional management scaffolding' really means?
