How to delete version by tag on GitHub?

Question

git

I accidentally mixed up and pushed code from another repository to github. Those. it should have been:
A → AA
B → BB
A did B → AA.
For versioning I use tags, for example:
git tag 0.0.01
Now the question is: how to destroy this left branch?

Answer 1

It works but not for my
case

git tag -d {release-tag-name}
git push origin :{release-tag-name}
