In order for an expert to easily find the projects he/she has to coach, you can associate him/her with one or more projects.
🚨 By default, all experts can coach all projects. In the experts space, in the tab "coaching session" it is possible for them to declare a session for any project.

From the experts tab:
👉 Go to manage program
👉 Click on the "staff" tab then on the other tab "Experts"
👉In the last column "Actions", click on the three dots and "Add project"
👉 A pop-up page will appear and all you have to do is select the projects of your choice.
