Azure CLI update metric alert with custom properties

Question

I have a series of metric alerts in azure that I would like to add custom properties to the action group. I have manually added some test data to one of the alerts, and when I use the CLI to pull the details for this alert I can see the data in the returned JSON :

az monitor metrics alert show --resource-group 'MyGroup' --name 'MyAlert'
{
  "actions": [
    {
      "actionGroupId": "/subscriptions/XXX/resourceGroups/MyGroup/providers/microsoft.insights/actionGroups/MyAlert",
      "webHookProperties": {
        "ResourceName": "MyResourceName",
        "TestData": "test"
      }
    }
  ],

I am trying to add similar data to other alerts using the update command, but I cant see any examples of how to add these WebHookProperties to existing alerts.

az monitor metrics alert update --resource-group --name 'MyAlert' --add actions ['Test','Test']

Any help is much appreciated!

I am trying to add similar data to other alerts using the update command, but I cant see any examples of how to add these WebHookProperties to existing alerts.

Here is the cmd to update the WebHookProperties to existing alert.

az monitor metrics alert update --resource-group 'RG-Name' --name 'MyAlert' --set actions[0].webHookProperties='{"ResourceName": "Venkat", "TestData": "Test"}'

Output:

After running the above command, the WebHookProperties are displayed using the cmd below.

 az monitor metrics alert show --resource-group 'RG-Name' --name 'MyAlert'
