A license is issued to you when you use Content in a design. Free Content licenses are issued at no cost. Pro Content Licenses are issued: (a) by paying, if you’re a free user; or (b) at no additional cost if you have a valid Canva subscription.

If you have a subscription, then a new license is automatically issued to you each time you use Content in a new design.
