Suggested change

	self, entity_ids: Iterable[str] | None
	self, entity_ids: Collection[str] | None

You could also consider using Collection instead. Something I learned recently, since Iterable doesn't include a __len__ method, bool(some_iterable) can always be True (in particular for generators).

Collection however will require __len__ to be implemented and thus enable a small shortcut later.

The difference in this case is probably negligible but since the method is called with sets anyway, you could also just use it.
