How to make Usernames case-sensitive?

Right now there can be a username with Test1 and a username with test1

That is not logical or efficient.

I’m not sure how to add case-sensitivity within the collection database.

I’ve tried the “contains” method instead of “is equal to” but that returns false negatives such as tes and test also becomes included in test1.

Can someone please help me do this?

You can think of making the username input type: “lowercase” in that case you prevent your users to add uppercase characters, so then you can use the is equal
