Fill out pipeline to determine the number of prizes awarded (at least partly) to organizations. To do this, you'll first need to $match on the "gender" that designates organizations.
Then, use a field path to project the number of prizes for each organization as the "$size" of the "prizes" array. Recall that to specify the value of a field "<my_field>", you use the field path "$<my_field>".
Finally, use a single group {"_id": None} to sum over the values of all organizations' prize counts.
