How do I specify the Django view action decorator for an endpoint with multiple parameters?

For the view and endpoint below with multiple parameters, how should url_path be specified for the action decorator?

urls.py:

router.register('utils', views.TableColumnViewSet, basename='TableColumn')

views.py:

@action(detail=False, url_path=r'???')
def table_meta(self, request, catalog=None, schema=None, table=None)

It's very difficult to find an example with multiple params. The trick is realizing that each parameter in the query string is a "named backreference". Realizing this, the syntax makes total sense: name each param as a backreference, with parentheses.

url:

http://0.0.0.0:8000/utils/table_meta/my_db/my_schema/my_table/

views.py:

Note the named group syntax: each param is surrounded with parentheses and the ?P<name> syntax names the group:

@action(detail=False, url_path=r'table_meta/(?P<catalog>[^/.]+)/(?P<schema>[^/.]+)/(?P<table>[^/.]+)')
def table_meta(self, request, catalog=None, schema=None, table=None)
