MongoDB find many objects from array, using array of matching id's

Question

I have an array structures as such

I've been trying to use an aggregation pipeline, and bulk.find() with a loop, and the $in operator, and none of these options seem to give me the power to (find many by an array of inputted id's). How do you find many objects in an array filtering by an array of ID's that I already have? I'm using PyMongo

Answer 1

Using an aggregation pipeline, use an $in match after unwinding

[
   {$unwind: "groups.asana"},
   {"source_id": {$in: ["id1", "id2", "id3"]}}
]
