How to remove cloned repository link from personal account?

Question

GitHub

I have a personal repository that has access to the development team account.
I cloned the repository via github desktop, made some changes, made a commit, decided to push, before that I got the pool back for changes and with some difficulties, but I kind of managed to push.
But when I looked at my personal repository, the very link to the repository clone from the developers account was copied to my personal repository, now the commit and push are also supported by the link to the repository. How can I get rid of this repository link in my personal account?
