GA4 API via Qlik Web Connector

[Mathias_Siebenbuerger]

Hey everyone!
Is there anyone already familiar with the new GA4 connector?
I want to pull some dimensions and metrics via the table "RunReport", but was not able to apply filters. 

The GA4 help page only provides the following, but that doesn't really help much for the Qlik Web Connector:

...
"dimensionFilter": {
  "notExpression": {
    "filter": {
      "fieldName": "pageTitle",
      "stringFilter": {
        "value": "My Homepage"
      }
    }
  }
},
...

Thanks in advance for your help!

Cheers, Mathias
