Build website -- 2

Hello, I am making a site with Learndash, I ask for a quotation to fix the following things that don't work: 1. The Addon GROUP REGISTRATION ([login to view URL]) creates Group Leaders during the purchase phase who are not authorized to create Group Code. 2. Create a Certificate with dynamic information + unique protocol number + qrcode to verify the validity of the document (I have installed [login to view URL] + [login to view URL] tracker-for-learndash) 3. View the Courses created with Learndash as if they were events, such as [login to view URL] I await yours. Thank you
