[Microsoft authenticator] How to customize the logo image for a service account

Question

Hi,

I am a developer and a user of authentication applications.
We have implemented TOTP-based two-factor authentication for our service.
Can you tell me how to customize the icon for our service account ourselves?
Please let me know if there is a way to send the logo image or provide it to microsoft.

P.S.
The purpose of my question is the same as this forum.

It would be great to know the current support status as it was not supported in 2017.
