Hello all!

I'm a student trying to learn the ropes of life, and along with that, learn spanish. I'm a native english speaker but have been learning spanish for about 6 years now. I was recently wondering if there was a generally accepted way to describe a non-binary person who uses they/then pronouns when speaking in spanish. For example, if I wanted to say "they are fun," would I said "usted es divertido"? "divertida"? is there another ending that wouldn't be taught in a traditional classroom? please let me know if you have any insight, thank you!!
