Confluence Cloud Migration Assistant (CCMA) doesn't have a way to stop stuck app migration

1. Issue Summary

Confluence Cloud Migration Assistant (CCMA) doesn't have a way to stop stuck app migration.

2. Steps to Reproduce

1. Create a plan to migrate an app following this KB for apps that have an "Automated path".
2. After the plan runs for hours (or even days) the spinning wheel animation on CCMA is still running with 0% progress. Same as the attached image.
   

3. Expected Results

Add an easy option on the UI to "stop app migration".

4. Actual Results

The plan gets stuck and even though the customer selected spaces to migrate and they were successfully migrated to the cloud they normally open a ticket to request "how to stop an app migration".

5. Workaround

Please contact the app vendor to get insights on how to stop their app migration.
