Digital Nomad Pay question

I should probably be reaching out to the embassy for this but I figured I'd ask people who may have gone through the DN visa before.

I see that it requires 10 mil yen salary, my question is how do I prove that?

I've moved jobs recently and while they are over that number I'm concerned that I may need to show a year of getting paid 10 mil before i can get the visa.

Thank you for any advice/experience shared!
