Description
I want to get all process group but just from the root canvas, when I call canvas.list_all_process_group(pg_id) I got all pg from all nifi. I am asking if there is any solution to get just from root canvas.
What I Did
playground_pg=canvas.list_all_process_groups(pg_id=root_pg.id)
There are canvas.get_process_group and canvas.get_process_group_status function, do either of those return what you're looking for?
