Should I send my scores to University of Chicago

My SAT scores are lower than the average (50%) of admitted applicants in UChicago. However, if I’m not mistaken, UChicago no longer requires standardized test scores like the SAT. Would it be better to just lay off? Also, would there be any “catch” for choosing not to submit scores (e.g. the applicant must fulfill something else if they opt not to send scores)?
