Azure Active Directory (AAD) does not have an attribute named 'company'. When you sync users to AAD, you configure a mapping of fields, typically the 'company' field from Active Directory (AD) is synced to the 'companyName' field in AAD. If you want this application to read information from AAD as opposed to AD I believe you will need to modify that field reference in your application code.
You could also store the appropriate information in one of the Extended Attributes and utilize that instead but that would still require modification of your application code.
