Hi there, I have a problem about alert webhook integration with slack.
My query of alert is the following
```
AzureActivity | where OperationName == "Update resource group" and ActivityStatus == "Succeeded"
```
And my JSON payload of webhook is here
```
{"text":"#A new resource group has been created. You can find the detail from <#linktosearchresults|OMS Search Results>"}
```
Then I got a webhook on my slack client and click the link defined "#linktosearchresults" to confirm the alert. But the query failed because there were some unwanted escape backslash in the query generated the link.
```
AzureActivity | where OperationName == \"Update resource group\" and ActivityStatus == \"Succeeded\"
```
Does anyone know the cause and the workaround?
