How to assign a tag to the orphaned commit in GitHub?

I have an orphaned commit produced by another person, and I see it in GitHub GUI. This commit is not accessible by cloning the repository as there are no branches/tags that contain this commit on the path. Assuming that the author of the commit has removed his local repository, I wish to assign a branch/tag to this commit directly in GitHub.

This commit can be seen just using a direct link that I can use because it's git hash is known. The commit is not seen in the Insights>Network however.

How can I assign a tag to the commit from this commit page in GitHub? Is that possible to create a new branch directly from this page? What are other ways to return this commit back in service?

Making an orphan commit cloneable again

Orphan commits that reside only on the remote (as long as garbage collection allows) cannot be cloned.

Through the Github web interface, using a direct link (e.g. https://github.com/<user>/<repository>/tree/<orphan-commit>) to the tree object connected to an orphan commit, you can access the Create Branch interface to create a new branch based on <orphan-commit> (which you already know the hash of) and make the object cloneable again.
