Power Platform Community Forum Thread Details

I have the following problem with user I would 
like to get to Team and extract the post offices 
via teammemembership_association. 
I am using the following statement with a Filter
ClearCollect(UfPo;
Filter(Utenti;systemuserid=MyUserid))


But if i do
ClearCollect(UfPo;
Filter(Utenti;systemuserid=MyUserid).'Team (teammembership_association)'.'Ufficio Postale')
goes wrong.

Can you help me?
Thanks
