New private key storage requirements for code signing certificates

Hello Community and Adobe 

With the new changes regarding private key storage requirements for code signing certificates https://knowledge.digicert.com/general-information/new-private-key-storage-requirement-for-standard-code-signing-certificates-november-2022 , we are no longer provided the private key only the .crt certificates.

It means that we are no longer able to recieve .pfx/.p12 certificates which are required by ZXPSignCMD to code sign plugins for Adobe products. 

What are we supposed to do to handle this from now on?
