[resolved] How to Track User Enrollment Status with Google Tag Manager?

I already have Google Tag Manager installed on my WordPress site. The URL for the course before and after enrollment is the same. I'd like to know how I can set up a tag in Google Tag Manager to determine if a user has already enrolled in the course.

Course link before enrollment: https://novoenvio.com.br/comunidade/course/comece-por-aqui/lessons

Course link after enrollment: https://novoenvio.com.br/comunidade/course/comece-por-aqui/lessons

Additionally, I'd also like to know how to track if a user has entered or made their first login to the community.
