How do I create a weblink for learners to self-enroll into a course via e-mail?

Hello Community,

I am creating 3 blended offerings available to a course, that consists of an ILT in each offering representing different days / timeslots for learners to join via Microsoft Teams and the ILTs have a maximum capacity of 30 attendees allowed.

Since this course is really a first come, first serve enrolment until maximum capacity has reached for each offering, I am looking for a way to just grab the weblink for this course, and sending out via an e-mail, where whoever clicks on the link first and enrolls has occupied a seat for this course.

I have heard about deep links, how do I grab the specific link for this course I have created? Do I need to turn any configuration on?
