I have extension table called c_task_extension which is an extension of Task table, in my lobbies whenever user clicks on a counter element i want the user to navigated to Task list screen.
For the user to be navigated to Task list screen i have added a navigation filter which will query the extension table as well, which looks like below.

I have added the relationship in custom metadata of Task table

any help on how we can join extension table in lobby navigation ?
