Surface Provisioning package

I need some assistance with MDM enrolment for provisioning packages. 

I can't find what credentials I should be using for building devices and thus after assistance please.

When this option for Enrol in mdm is off, some devices have gone into Intune and some haven't.  I can't think or see why this is happening.  They go into Entra but not Intune.  I thought this was a build issue with the devices but i've tried various i.e. upgrading from a Windows 10 teams room to Teams Rooms for Windows 11, and a build media of the New Teams rooms for Windows 11 but still the same issue.

I understand i need to complete this Enrol in MDM, so I need some assistance as to what credentials i should be using please.

Apologies, if this is a duplicate, for some reason i was certain i had published this yesterday but i can't see this post.
