Shopify: Remove product from collection via API call

I'm trying to use the Shopify API to remove products from a collection.

In the docs (https://docs.shopify.com/api/collect) overview it says:

DELETE /admin/collects/#{id}.json
Remove a Collect from the database

While when you jump to the description it says:

Remove a product from a collection
Destroy the link between a product an a collection
DELETE /admin/collects/#{id}.json

So can I use this to remove a product form a collection or remove a collection from the DB?

And if it's possible to remove a product from a collection - what I want to do - shall I pass the collection ID or the product ID - actually I think I have to pass both, or how shall it work otherwise?

Thanks for your help!
