Firestore Security Rules Regex

[Romeo Bahoumda]

I have trouble modifying my Regex expression to satisfy the rules semantics

I want it to check if the email matches a particular domain

so it looks like this

request.auth.token.email.matches(/^[A-Z0-9._%+-]+@(lehigh)+\\.(edu)$/i)

What should I change?

Im assuming you just want to allow all email addresses from the lehigh.edu domain?
should look like this:

request.auth.token.email.matches('/.*@lehigh[.]edu/') == true;
