Overall lgtm!
1). Let's ensure CI passes and
2). Let's also ensure if dataSource is invalid like serverless collection, it is handled properly. In that case, we can show the empty findings, alerts, detectors and correlations list.
3). I believe we are not using any other plugins API is SA, but if we are then let's make sure that integration is working as expected.

I will be working on points 2 and 3 in the next PR where I handle the cases related to unsupported DS selection
