Deploying bot channel registration New-AzResourceGroupDeployment CHANNEL_NOT_SUPPORTED

Hello,

I'm trying to automate bot creation on Azure using powershell.

I 'm able to create an Azure application using New-AzureADApplication command.

I'm also able to create an AzureBot  using New-AzBotService command.

Now I'm struggling to add a new channel registration, the Microsoft Teams channel. The command New-AzResourceGroupDeployment command returns the following error (correlation ID : 3ca89268-5443-45f9-96e6-6f5cfd1a7e57)

PS C:\Users\XXXRoot> New-AzResourceGroupDeployment -ResourceGroupName $ResourceGroup.ResourceGroupName -TemplateFile $PathTemplate
New-AzResourceGroupDeployment : 10:52:44 AM - The deployment 'ChannelTemplate' failed with error(s). Showing 1 out of 1 error(s).

I didn't find anything on this particular error (CHANNEL_NOT_SUPPORTED).

Here is the template file I used :

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "resources": [
	  {
		  "condition": true,

		  "location": "global",

		  "properties": {

			"properties": {
				"callingWebHook": "https://server:port/route",
				"enableCalling": true,
				"isEnabled": true
			}
		  }
	  }
  ]
}

Can someone help me ? Not sure I understood everything about New-AzResourceGroupDeployment command.

Regards,
