Linking to Jira Tickets

According to the docs, Gitea should be able to recognize Jira Ticket ID commit messages and generate hrefs for them, right?

So I’ve set up the url format of my external issues to something like

https://<myjira>/projects/PROJ4ME/issues/{index}

and naming convention to alphanumeric.

However, a commit message like ‘PROJ4ME-123’ is not recognized and rendered as href.

Am I missing something here?
