I cant quite get this to work.. 

I have two tables that have a many to many relationship. I'm trying to clearcollect and create a string of names from the second table..

the second table 'Users' is the dataverse systemusers table. 

e.g.
 
ClearCollect(
    colMetricSummary,
    AddColumns(
        ELT_Metrics,

        AssignedUsers,

        Concat(ThisItem.Users, 'Full Name', ", ")
    )
)

    In Dataverse, you cannot add custom columns directly to a native Many-to-Many (N:N) relationship table because it is an internal "intersect" table managed by the system. This internal table only stores the unique IDs (GUIDs) needed to link records. 

    If you need to store additional data—such as a "Date Joined" or "Status"—associated with that relationship, you must use a Manual Many-to-Many relationship instead
