Unable to access Dev Tier in Mexico — Associate Application Developer exam code request

Hello,
I recently passed the Palantir Foundry Aware Certification with a score of 93%, and I am now preparing for the Associate Application Developer Certification.

I do not have a Palantir point of contact. I understand that AIP Developer Tier users can normally request an exam code by submitting an “Account Questions” Foundry issue through their Foundry instance.
However, when I attempted to sign up for AIP Developer Tier, I received a message indicating that sign-up is currently not available in Mexico, so I am unable to access Foundry Support through that route.
Could someone please advise me on the correct process for requesting an Associate Application Developer exam code or voucher in this situation?
Thank you!
