Managing domains in multiple-domain tenant in Microsoft 365

Microsoft

Dear everyone, 

I have a customer whose tenant with multiple domains in Microsoft 365. How could my customer assign an admin who manage a specific domain, and he/she cannot manage other domains in this tenant. 

Please help advise in this scenario. 

Thanks.

The devil is in the details, but Microsoft's built-in functionality for this scenario (administrative units and custom roles) only addresses some admin features/some services. Your best bet it to look at third-party tools that offer "admin portal replacement" type of solution.
