How to report this mistake

[Screenager]

In the additional family information form as part of the visitor visa application for my parent, I discovered this tiny mistake:
For 2 of my siblings (parent's kids), I wrote Daughter where I needed to write Son, and Son where I needed to write Daughter.

Everything else is correct. Should I inform IRCC of this mistake? If so, how.

My parent gave biometrics 8 days ago. I was just randomly looking at the application forms and just saw the mistake.

They can send a webform with correction.
