To disable the integration between Jira and Stack Overflow for Teams, head over to your Jira instance, and navigate to Jira settings > Apps > Manage apps.
Select the Stack Overflow for Teams app from the list of installed apps and click Uninstall.
Once you’ve uninstalled the app, Jira links within your Team will no longer show a preview of the Jira issue. and the search glance will disappear from the sidebar on Jira issues.
If you want to reactivate the integration again, simply reinstall and reconnect the Stack Overflow for Teams app.
