Hi All - just posting this because I spent all day researching posts to find this answer. In the end I ended up taking a piece from about 4 different posts to put together this extremely simple solution for finding team members in a Dynamics team. The trick here is that the temmebership table is hidden so you find it to query on. This simple solution worked for me - hope it helps you.
The Filter Rows is (teammembership_association/any(t:t/teamid eq 'xxxxxxxxxxxxxxxxxx'))
Clearly I don't need the List Rows - Teams above ... just illustrating the starting value
