Where is IntelliJ Idea coupon inside the course 'Spring Boot: Mastering the fundamentals'

In the course description, it is mentioned that:

A Special Gift for You

Exclusive Bonus

When you enroll in this course, you’ll get 6 months of IntelliJ FREE!

IntelliJ is a powerful, intelligent IDE that makes coding faster and more enjoyable.

Use the coupon provided inside the course to claim your free access.

Now my question is where is the coupon? And how should I use it to install IntelliJ Idea ultimate edition?

Also we are missing the Spring Boot category in this discussion forum.
