Can scriptrunner prevent branch deletion through the UI?

Question

Is there a way to use ScriptRunner to prevent branch deletion performed through the UI? (for stash versions prior to 3.10 which don't have this support built-in).

I can see it's possible with a pre-receive hook, but I think this wouldn't prevent a delete through the UI. I had a look through the event hooks but I couldn't see a CancelableEvent for branch deletion.

(I do have available other standard actions in response to events)

Hm - I don't have "Custom event handler" available - is that because it's not enabled for me for my repo, or is this not possible at the repo level?

Ah, thank you! The link to this from the adaptavist documentation was broken (I see you have fixed this now - thank you) and my own googling 'Atlassian CancelableEvent' took me here which on reflection is obviously (from the URL) out of date.
