Issue Summary

After upgrading to JSM 5.3 and above, all users will see a pop-up like this: 

As an admin, I would like to disable or dismiss the pop-up for all users, even those who haven't seen it yet.

Workaround

It's possible to disable the pop-up entirely for all users by enabling a feature flag.

1. Open the feature flags page in Jira.
2. Add this flag: never.display.assets.rebrand.onboarding.enabled
3. Save change.
