How to know which packages use Integration Service?

How to know which packages use the Integration Service connections and which do not? Is there a table somewhere that tells us which packages use it, and which activities are exposed? In manage packages, is there anything in the description that would tell us? Perhaps a dependency? In the activity, how to know which connector/connection it is using?

Is this what you are looking for

Yes, I saw that. But where is GMail? Where is Microsoft One Drive? You can see my confusion.

@Terry_Marr

I agree few are missing as it a a growing list

Best place to check is going to connectors page of integration services
