Is the AWS Certified: Associate Challenge Coupon Applicable for the ML - Associate Standard Exam?

Hello there, I recently received a discount coupon through the AWS Certified: Associate Challenge. I'm aware that the coupon isn't applicable for beta exams. However, I noticed that the Machine Learning Engineer - Associate exam was included in the list provided in the email when the coupon was shared. https://pages.awscloud.com/GLOBAL-ln-GC-Traincert-Associate-Certification-Challenge-Registration-2024.html?trk=456d00ea-1c9e-4704-a231-572f5d24f010&sc_channel=el

As I'm particularly interested in pursuing the ML certification, I was wondering if there's an option to apply the coupon code to the ML - Associate exam once the standard version is released after the beta period.

Could you please clarify if this would be possible? I would greatly appreciate your guidance on how to best utilize this opportunity. Thank you for your assistance!
