Change "Allow public client flows" property of Azure AD apps via PowerShell

Some time ago I wrote about several problems related with changing of "Allow public client flows" property of Azure AD apps (on the moment when this post has been written this property was called in UI differently "Default client type > Treat application as public client". Nowadays it is called "Allow public client flows"): Several problems when use Set-AzureADApplication cmdlet with AzureAD app with allowPublicClient = true.

The problem was that it was not possible to change this setting from PowerShell script via Set-AzureADApplication cmdlet. However it is still possible to change it from script (solution was found by Piotr Satka so all credits go to him) - you need to use another cmdlets Get-AzureADMSApplication and Set-AzureADMSApplication. Here is the sample:

$azureAdMsApps = Get-AzureADMSApplication 
$azureAdMsApp = $azureAdMsApps | Where-Object { $_.AppId -eq $appId }
Set-AzureADMSApplication -ObjectId $azureAdMsApp.Id -IsFallbackPublicClient $value | Out-Null

Using this code you will be able to change "Allow public client flows" property for Azure AD apps via PowerShell.
