Apply for Microsoft Trusted Root Program

Dear team,
I am writing to you on behalf of BORICA, a Qualified Trusted Service Provider in Bulgaria, listed in EU Trusted list (https://webgate.ec.europa.eu/tl-browser/#/tl/BG).
We would like to complete the Microsoft Trusted Root Program application form at: https://learn.microsoft.com/en-us/security/trusted-root/new-ca-application via https://aka.ms/rootcertapply but we are not able to find it. This link leads us to https://learn.microsoft.com/en-us/samples/browse/?redirectedfrom=TechNet-Gallery but there again we can not find the form.
Please advise us how to proceed in order to find and fill the form.
Thank you in advance for your cooperation.
