How can we commit changes using the access token key that gets generated using oauth support in gitHub

How can we commit changes to github using the access token generated using github Oauth.

I have got the access token and able to clone the repository using the code below
CloneOptions options = new CloneOptions();
var creds = new UsernamePasswordCredentials()
{
Username = "access token"
Password = string.Empty
};
CredentialsHandler credHandler = (_url, _user, _cred) => creds;
options.CredentialsProvider = credHandler;
string clonedRepoPath = Repository.Clone("repository", repoLocation, options);
repo = new Repository(repoLocation);

But unbale to commit the changes using the access token. below code fails with the error "'request failed with status code: 403"

Commands.Stage(repo, "abc.txt");
Signature sig = new Signature(new Identity("name", "email"), DateTimeOffset.Now);
Commit commit = repo.Commit("", sig, sig);

        // Push to remote repository
        var creds = new UsernamePasswordCredentials()
        {
            Username = "access token",
            Password = ""
        };
        CredentialsHandler credHandler = (_url, _user, _cred) => creds;
       
        var fetchOpts = new PushOptions { CredentialsProvider = credHandler };
        repo.Network.Push(repo.Network.Remotes["origin"], "HEAD", @"refs/heads/master", fetchOpts);

Expected: Should be able to commit changes using access token.

OSx, .net core 5.0

issue 内の CloneOptions と PushOptions の認証情報設定から始め、.NET 5.0 上で LibGit2Sharp 0.26.2 を使用します。Network.Push の呼び出し中に 403 を再現し、関係する remote、refspec、認証情報を調査します。OAuth token を使用して、staged された変更を commit し、GitHub repository に push できれば完了です。
