Issue adding HMRC Agent Account to QuickFile

I’m experiencing an issue when trying to connect our HMRC Agent Account to QuickFile.
During the authorisation process, HMRC requests additional identity verification, but the only available verification methods are a UK passport or a UK driving licence(I have Polish passport). We have already spoken with two different HMRC support departments, and neither could explain why this additional verification is being requested.
We suspect the issue may be related to the fact that the QuickFile account is registered under one company, while we are trying to connect the HMRC Agent Account of another company (both are part of our organisation).
Could you please confirm whether the QuickFile account owner can affect the HMRC authorisation process? If so, what would be the correct way to configure this?
Thank you in advance for your assistance.

Hello @macuser

Could you please confirm whether the QuickFile account owner can affect the HMRC authorisation process?

This is not the case. During the authorisation process you are redirected to HMRC and the authorisation process is done on their end with their sytems/processes, once complete an access token is passed back to us from them.
