Edit Language of premium theme & tutor lms

My theme and tutor lms use language like, “instructor” and “student”
I want to change this but I’m not sure who’s calling the shots..or are they both?

I’ve found the code via google inspect, but since I can’t update the core files (or know it’s a bad idea) I’m not sure how to do this. Ideally, I could change it once and it’d apply eveywehre but idk if thats an option.

I’ve been able to change the color via additional css but changing copy is proving more difficult.

Here’s an example of an instance i’d like to change

<a class=”tutor-button” href=”https:// websiteURL.com” >Register as Student</a>
