Question about the method ListFolderMembersAsync()

Question

I noticed an issue when I call ListFolderMembersAsync(sharedFolderId).
If my shared folder contains a member that it is external of my team, when I call this method ListFolderMembersAsync, it doesn't show this member on the list of members.
What am i doing wrong?

Thanks for your reply.
I discovered the problem. In my scenario the folder contained some members and some invitees.
When I called ListFolderMembersAsync I checked inside only the Users but not the Invitees.

Thanks for your assistance
