"Connect Courses" versus "Explore Courses"

Long time user of Connect for biking and hiking. Many, many Courses developed, and Activities logged. 

Just added Explore for InReach2 usage.

Can these original "Connect Courses" be accessed by "Explore Courses"? Or exported to "Explore Courses"? If so, how to do?

Same questions for "Connect Activities"?

Thanks in advance!

PS - Would be nice to combine these "somewhat similar" apps?
