Pre-arrival Rapid Test for Children in Gateway

Does any know if children (with vaccinated parents) can use a 'rapid antigen' COVID test result in the Gateway Portal Application. I understand the arrival test would be a PCR, but I was wondering about the pre-arrival test?

Got an answer from Henrietta. All unvaccinated travelers, including children, must have a pre-arrival PCR test when completing the Gateway Portal. The approval of a pre-arrival 'rapid antigen' test is for vaccinated travelers only.
