Certificates in other places

Dear Opigno Crew, I am using a stripped down template for a very slim version of Opigno. A custom module provides me with handcoded progress messages on the frontpage (like 'Hello User, you are in Module 3-2 of 6). However I would like to display a certificate on the frontpage if the last course is finished. Any recommendations how I should go about that? thanks in advance and thanks for developing such a classy distribution Matthias
