How do I get the latest unsubscribe customers using the v3 api

Hello,

I've been trying out your api and seem to have run into an issue. When I fire: https://api.cc.email/v3/contacts?status=unsubscribed&updated_after=2022-05-01&limit=500
It only shows 10 or 15 contacts who have unsubscribed. However, we have had a large amount unsubscribe since the 1st of May, so much so that it was in the 100s. How come there is a "updated_after" parameter, but no "unsubscribed_after" or anything that would just let me see the LAST 500 starting from TODAY backwards until we hit 500?

I've read all of your API documentation and there doesn't seem to be a solution.
