Create new alert in Learning

Summary

Create alert to notify a learner about renewal course

Content

The client has a specific course, which expires every 3 years.
The HR Specialist would like to send a notification or email to learners 30 days in advance for renewal.

When building the alert, I had doubts about which resource / attribute I should use to create.

Does anyone have any documents they can share?
Is there a document that explains the meaning of each attribute?

Thank you
