Push to release branch based on tag created on master branch

Here is what I am trying to achieve

  • My repo is currently connected to Vercel for automated deployments
  • I have two branches master and release
  • The master branch is the current connected to a staging URL on vercel like staging-example.vercel.app
  • The release branch is connected to the production URL like example.vercel.app
  • Whenever I create a new release(via the GitLab release page) on the master branch with a tag, the pipeline pushes that code the release branch which in turn is picked up and deployed on the production instance.

The current pipeline as shown below is able to achieve this but I am not entirely sure if this is the correct or the better way to do. Any advise is highly welcome and most appreciated.
