Before you assign it

Microsoft labels this a privileged role, so make it eligible through PIM rather than permanent, require phishing-resistant MFA to activate it, and review who has it regularly.

What it can do

PermissionWhat it allows
microsoft.directory/domains/allProperties/allTasksCreate and delete domains, and read and update all properties
microsoft.office365.supportTickets/allEntities/allTasksCreate and manage Microsoft 365 service requests
microsoft.office365.webPortal/allEntities/standard/readRead basic properties on all resources in the Microsoft 365 admin center

Assign it

The role ID is the same in every tenant, so these work as they are. Make it eligible through PIM:

powershell13 lines
Connect-MgGraph -Scopes "RoleEligibilitySchedule.ReadWrite.Directory"
$user = Get-MgUser -UserId "jane.doe@contoso.com"
New-MgRoleManagementDirectoryRoleEligibilityScheduleRequest -BodyParameter @{
    Action           = "AdminAssign"
    Justification    = "Needs Domain Name Administrator for <reason>"
    RoleDefinitionId = "8329153b-31d0-4727-b945-745eb3bc5f31"
    DirectoryScopeId = "/"
    PrincipalId      = $user.Id
    ScheduleInfo     = @{
        StartDateTime = (Get-Date).ToUniversalTime().ToString("o")
        Expiration    = @{ Type = "afterDuration"; Duration = "P180D" }
    }
}
