Moving Certification from one account to another

Hello everyone

I have the following problem.

I have two MS accounts:

Account 1 is my private one
Account 2 is my work account

Now I have done all certifications on my private account (account 1)

Last week I accidentally did the DP-600 certification on the work account (account 2)

I would now like to move the DP-600 certification from my work account (A2) to my private account (A1).

How can I do this?
