Tagging a git repo using jenkins pipeline script

Question

I am trying to tag a git repo using Jenkins pipeline script. I am very new to jenkins pipeline script.

Is there a command like the one below, to tag the branch, which is used to checkout the branch

git branch: 'master',
  credentialsId: '12345-1234-4696-af25-123455',
  url: 'ssh://[email protected]:company/repo.git'
