Recommendations for form validators that go well with graphql-ruby?

Hey everyone, we're working with graphql-ruby and reform right in our app right now, but I'm finding that while reform is good with form submissions, it's a bit more complicated with mutation and graphql input objects. So, I was wondering if there are any recommendations for trailblazer alternatives with good documentation that feels intuitive with graphql-ruby, and doesn't need a book to understand and read.

Would love to hear the experiences of those who use graphql-ruby and a validator!

Thank you!
