Triggered email code! Need Help!

I was able to set up the email in WIX and I was given the code to put on my page, but I don’t know on what line to fill in the code, and how to fill in the fields. I son’t want to use a third party for my emails like sendgrid. Can someone help me? I do not have a background in coding at all. This is the code I was given:

wixUsers.emailUser(“QsKHpr7”, );
