FlutterFlow authentication in firebase and other collections or table in supabase.

I am using Firebase Authentication in my app but some of my collections are hosted in Supabase. I need to validate my Supabase requests and so I want to pass my JWT token as header in my Supabase requests. I know I can do this if I create an API call to Supabase. But as FlutterFlow already has a Supabase Integration, is there anyway I can pass my JWT token as header there? I see no option of adding my JWT token (or header) in the Supabase section in FlutterFlow.
