I Cannot Push it to the branch that I have created earlier according to the steps given.

[Pavan-Virat-18]

Problem:-
$ git push -u origin new-pavan-branch
remote: Permission to firstcontributions/first-contributions.git denied to Pavan-Virat-18.
fatal: unable to access 'https://github.com/firstcontributions/first-contributions.git/': The requested URL returned error: 403

Please suggest steps to resolve this issue.

Looks like you are attempting to push to the main branch of the repo.
Make sure you:

1. Have forked the repo.
2. Clone your forked repo to your environment.
3. Create a new branch in the forked version.
4. Push to your forked branch
