Yes, you are required to invite your counselor.
Below your counselor info it should either have a box that says ‘enable preview’ like you see on the first screenshot below (circled in red), or a box that says ‘disable preview’ (screenshot 2).
If the box says enable preview, you are ok, because you didn’t give your counselor access to see your entire app. If you did enable preview for your counselor, then you would see the disable preview box…so you could reverse that if you want. Does that make sense?
