the jenkins agent i m using is a server on which i cannot change credentials(ssh keys and stuufs) nor add the existing key to my github

Im trying to use a string parameter to add a token , which value i ll paste when building the job
I don t want to store my git credentials on that jenkins server either, and all the syntaxes i ve used so far are not working.

sample of jenkinsfile

i was expecting to save the value of the token in the TOKEN variable and call it in my git push command

i m trying to avoid to use the env variable calling the credentials stored in jenkins.

thx in advance if anyone has a clue.
