Adding a new personal access token or updating the previous one?

Hi everyone, Utkarsh here.I had added a personal access token with read and write registry scopes in GitLab while working on a project but now I want to change the scope which should include API as well. So is there any way by which I can change the scope of my existing token or have to make a new one? If I have to make a new one how to add it to my project?
