Hi Martin,

You actually can create a new group (invite only or closed group) and create the task inside the group, where the task inside it only viewable to the members

Hi Muhammad
I have to specify what I have determined.

I am logged in as user A. User A is not a member of the Team X group.
As user A, I look at the profile of user B. User B is a member of the Team X group.
As User A, I see the APP Tasks of User B under menu entry Tasks. As User A, I see the tasks of User B, which he has been assigned in the closed group Team X. see screen shot
This should not be possible. What are you thinking about that?
Best wishes
Martin
