Hey @marioantonini Fantastic work. From testing on my repo, everything appears to be working as intended:

• Author matches assignee, no Draft: message reminder to add Draft
• Author matches assignee, w/ Draft: typical message posted
• Author doesn't match assignee, w/ Draft: typical message posted
• Author doesn't match assignee, no Draft or Prework: assignee is un-assigned w/ message
• Issue is labelled Complexity: Prework: typical message posted

Thanks once again for your changes and for working on this!
