Once you receive the notification of acceptance, you are invited to modify and re-submit your full paper, taking into account the remarks of the reviewers.
Just go to the profile page and upload by May 16th, 2022 a single file including first a short explanation of how the modifications performed answer the reviewer comments and next the modified version of the full paper.
If you forgot your reference number to log in, ask it to the secretary.
Once this step is done, the modifications will be checked by the TPC and you will then be able to submit the final camera-ready version of your paper.
