What I did is that I added text inside Self Enrollment. Therefore, before enrollment (Enroll button), use can see custom text in Bold.
Temporary, this solve my issue.
For example, inside my organization, for a particular training lets say Angular Advance, I want user to know that this training is for Developer and I agree that I am aware of Angular Basics.
So before enrollment user will see -
"I agree that I am Developer and I am aware of Basic Concepts of Angular"
Them inside mail section of self enrollment, we have configured custom email text that send garment in email.
