make a specific dashboard only viewable to a group of users

We want to make a specific dashboard only viewable to my team. What I did is to create a sub folder in the shared folder and try to include my team to view the folder( via manage content icon) The error is that I cannot remove the user who can manage / edit the parent folder ( the shared folder). Is there any way to solve this issue?
