Get only the collaborators, not the owners of the ORG of the github repo

I have Github Organization with the owners Owner1 and Owner2 and members Member1 and Member2. Now I created a new repository in this Organization and added two users as collaborators (user1 and user2) of this repo.

Now the result of postman with the below GET request will result in the following:

Owner1
Owner2
user1
user2

POSTMAN request : https://<github-host>/api/v3/repos/<my-gihub-org>/<my-github-repo>/collaborators?per_page=100

But I am interested in listing only the collaborators i.e., user1 and user2 ; Not the owners .

Could someone please help me here…!
