Is it possible to delete a published hotfix branch?

Question

git

There is an old version of git flow in which you cannot create more than one hotfix.
I sent the hotfix with the command git flow hotfix publish [name]
This branch has not yet been merged with a fight, I need to create another hotfix, but I'm afraid to delete the current branch, suddenly the changes will be lost.
And how to update git flow? Google doesn't turn up anything for this query.

Answer 1

Is it possible to delete a published hotfix branch?

git push origin --delete serverfix
Where origin is the name of the remote repository and serverfix is ​​the name of the branch.
Use the console. All gui applications either do something completely trivial or for noobs.
What's the fight? Corporate slang? The common name for the master branch is master
