How do I create a course enrollment button?

Question

Learning Management Systems

Hello!
There is a calendar of courses with the possibility of their purchase.
I want to create a button to apply for a course. Is it realistic without writing your own plugin?
If not, in which direction should we move?

Answer 1

Describe the task in more detail. Do you need just a button or a button+ that performs an action and sends a ticket to your inbox?
What should be the end result?
