OAuth against Jira Server

We run an on-prem Jira Server and an on-prem Sentry and are looking into getting the two synced up (Global Integration).

The setup, for some reason, only OAuth’s via the user who setup the integration, instead of allowing each user to OAuth and use their own identities.

Is there something that we’re doing wrong or is this how Sentry’s Global Integrations are intended to work?
