i can't sign in to my bussiness account office 365

Question

My problem, in short, is:

I have a Microsoft Business Office 365 account

I added this account to the authenticator app by scanning the QR code initially when registering the account

 in this link

https://developer.microsoft.com/en-us/microsoft-365/profile

My problem

1- I did not save the QR code that I used when registering for the first time

2- I did not add a backup email or phone number to contact in case a problem occurs

 

Now I cannot add my account to the app because I do not have anything of what I mentioned

Every time I try to log in, I am asked to approve the request through the authenticator app

Unfortunately, I cannot add this again even though I have the password for my account

Now I have two questions

1- Either I find a solution by adding my account again to the authenticator app

2- Or if I find a way to open my account without having to use an authenticator app

 

Unfortunately, I contacted customer service many times and did not find a solution

Can someone help me log into my account again?
