Sorry to disapoint but currently there is no such log available.
If the IMAP log is configured at Protocol Level than you may check for adding DELETE flag and later on EXPUNGE the message(s) - example below for removing one message from Spam folder.
Do you have any Idea for the specific date for the new release?
The tentative release was 4th Quarter of 2021.
I am waiting for the Labels and Permanent Flag for IMAP.
