How to delete a plan

Dear Reader,

I have crated a plan and due to another MFA browser extension using FIDO2. There was something weird happening which caused the plan creation process not to complete. I removed the browser extension from the the browser and could create a 2nd plan which complete in the creation process.

I have now a working plan and an incomplete plan (2 different IDs). I would like to clean up the incomplete plan but cannot locate how to delete the incomplete plan.

Can you advice how to proceed?
