New-AzADApplication returns Az.MSGraph.internal\New-AzADApplication : Insufficient privileges to complete the operation

### Description

Hello.
I want to create a SAML app using application template ID for custom apps - 8adf8e6e-67b2-4cf2-a259-e3dc5476c621, I use
`New-AzADApplication -DisplayName test-ag-asdsa2 -ApplicationTemplateId 8adf8e6e-67b2-4cf2-a259-e3dc5476c621` but receive this error:
```
Az.MSGraph.internal\New-AzADApplication : Insufficient privileges to complete the operation.
At C:\Program Files\WindowsPowerShell\Modules\Az.Resources\5.2.0\MSGraph.Autorest\custom\New-AzADApplication.ps1:702 char:5
+ $app = Az.MSGraph.internal\New-AzADApplication @PSBoundParameters
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: ({ body = {
"...reADMyOrg"
} }:<>f__AnonymousType6`1) [New-AzADApplication_CreateExpanded], Exception
+ FullyQualifiedErrorId : Authorization_RequestDenied,Microsoft.Azure.PowerShell.Cmdlets.Resources.MSGraph.Cmdlets.NewAzADApplication_CreateExpanded
```

New-AzADApplication work well if I don't use -ApplicationTemplateId parameter. So I'm not sure what privileges are required and where should I specify them, because I logged in using my uesr account, not SP.
