Create Detection Rule from query

Hi, I'm new to creating queries with KQL and now testing some queries to extract some insights, from the TVM. So I've got a simple query to extract the total number of vulnerabilities found by TVM, which is this: DeviceTvmSoftwareVulnerabilities | summarize count() by VulnerabilitySeverityLevel | order by VulnerabilitySeverityLevel | render piechart I would like to receive an Alert with the results of this query each day 1 of each month, so I can start to understand some progression. But if I try to create a detection rule based on this query it says that I need to return the required columns "Timestamp" and "ReportId". How can I add those without impacting my end goal? Thanks
