Filter request property parameter based on Identity uid

Environment: 1IM 9.2, Angular Web Portal

I need to filter a request parameter  with value definition Table so only results for the current user are shown (example: GroupMemberships for the current user), for this i use the condition (query)  on the value definition tab for the parameter

how can i write the query for this case ?

I've used UID_Person='%UID_person%' but no result is retrieved, i would assume the error is on the  %UID_person%' syntax

thanks in advance
