How to release the final assessment so it is visible for the participant

It is an active choice to release the final assessment, which has been agreed upon by the assessors. This release of the final assessment has no influence on whether or not the assessor has chosen to share his/her personal annotations and comments in the assessor tool. The one can be shared without it affecting the other. 

You release the final assessment in the pane "Assessment" in the participant list at the bottom of your flow. To your right you see a column called "Show". When you tick this box, the final assessment will be released once the assessor end time has been reached.
