OTP app problem

I have a question , i enable 2FA with OTP app method .
for one user they delete OTP from google authenticator and now link or QR code expired ,
how we can generate new QR code for this user ,
i try to enable disable 2FA and enable disable that particular user but we don’t receive QR code email for that user any more .
How we can generate QR code again ?

Hi , the only way I found was to reset the OTP password via administrator account.

However I would like to give that permission for the IT people that I have.

anyone knows how to do it ?
