Certificates can be obtained in a couple of ways.
If you wish to purchase a certificate for yourself, navigate to the 'Courses Completed & Certificates' tab, locate the specific course, and click on the 'Claim Certificate' button which will direct you to the Alisoin shop.
Alternatively, you can access the shop by selecting 'Get Certificates' on the sidebar to the left.
Your manager might also purchase certificates for team members, which they may wish to allocate to you.
