Add Azure Web App diagnostic log settings to ARM template - azure

Question

I'm looking for the option to enable diagnostic log settings (file level, not blob) on the template deployment stage.
I've found the following example on Github however, it doesn't work, saying "Microsoft.Web/sites/logs" is not a valid option".
Below is the part of my template:
{
"apiVersion": "2015-08-01",
"name": "logs",
"type": "config",
"location": "[resourcegroup().location]",
"dependsOn": [
"[resourceId('Microsoft.Web/Sites', parameters('siteName'))]"
],
"properties": {
"applicationLogs": {
"fileSystem": {
"level": "Verbose"
}
},
"httpLogs": {
"fileSystem": {
"retentionInMb": 100,
"retentionInDays": 90,
"enabled": true
}
},
"failedRequestsTracing": {
"enabled": true
},
"detailedErrorMessages": {
"enabled": true
}
}
},
Also, I've found the following discussion on a similar question but the topic starter stated that this piece of code works correctly in most cases.

If you want to enable diagnostic log settings during deployment Azure WebApp. You could use the follow demo code to do that. It works correctly on my side.
