How to get a check on teacher dashboard from a multiple choice question

Hello! I am new to the CL on Desmos. I am creating an activity where there are multiple-choice questions and I have figured out how to show the students they are right or wrong within the page but I want a quick way to make sure that they are getting it right or wrong on the teacher dashboard with the check or x, not the dot. any help is greatly appreciated on how the code will look or what to type. Thank you in advance.

You have to use the sink correct on the checkbox

Thank you! I got it to work!
