Okay but now how do you recommend I hook up my Sentry instance to create tickets in Jira, now that Jira has deprecated long-lived keys and I have to refresh my token every 6 weeks or whatever. It needs long-lived access. Whether that comes in the form of a OAuth refresh token or a key is not particularly interesting or important, IMO.
You do what you can. Eliminating long-lived keys isn't always possible; you set up rotation instead.
