How to get one specific commit out of squashed and deleted branch?

Commits squashed via GitLab Merge Request while merging into main,
also the delete branch after merging option was enabled.

How can i get one specific commit out of deleted branch?

I tried this : git - How to unsquash a commit? - Stack Overflow

But git reflog gives me nothing squashed.
Is it even possible?

Hi @User4567,

Do you still have that branch on your local environment or the specific commit hash? You could use the hash and use git cherry-pick.

I edited files in the GitLab Webinterface, so i do not have that branch locally.
