What is the web equivalent of git tag -f <tag-name>?

I am learning the git tag command and its options and I started using the git command line client.

Then I moved to the Gitlab web interface and started creating lightweight and annotated tags; but then I found that there’s no way to update an existing tag, because a Tag already exists error is shown.

Is there an option that I missed? Or is it really forbidden to change existing tags from the web (without deleting them beforehand)?
