The documentation https://developer.atlassian.com/cloud/confluence/frameworks-and-tools/ states for ACE (and AC spring):
These frameworks handle tasks like JWT authentication and signing, persistence of host details, installation and uninstallation callbacks,
However ACE does not handle the uninstall callback. There is an open issue https://ecosystem.atlassian.net/projects/ACEJS/issues/ACEJS-33 , but it’s open since 2016.
Edit: opened issue https://ecosystem.atlassian.net/projects/ACEJS/issues/ACEJS-149
My question is: How to handle the uninstall callback? Any examples?
