App Developer account update

Hello, We do have an active developer account but the current developer owner/admin passed away. We can't access the developer account anymore to update the app or change the ownership. We do have a username/password but due to the fact it has 2FA we can't access the owner/admin account as we can't access the owner's mobile SMS.

Please help us to process the next step as we need to continue to update the app under a new admin.

I am sorry for your loss, you should contact Apple, but looks like you don't have access to anything what could possibly confirm your identify. Do you have any device with that Apple ID still active?

Yes, I had sub dev account under the apple main dev account.
