Issue Summary

Currently, not all tabs can be hidden or made default in Jira business projects, as outlined in our documentation:

• Customize the navigation in your business project

Suggestion

If admins could perform those actions for any tabs, say, keeping at least one tab available, it would be great for further customization. 

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
