Unable to get data from MS Graph integretion

Hi!

So, I followed the steps in Configure Microsoft 365 in a copy activity - Microsoft Fabric | Microsoft Learn in order to read data through MS Graph Data Connector. It seems to work just fine, no error messeges, pipeline execution time is about 25 mins and it creates a table in the lakehouse with all metadata such as columns and datatypes as expected. However, the table is empty.

This is the output from the pipeline execution:

{
"dataRead": 0,
"dataWritten": 0,
"filesWritten": 0,
"sinkPeakConnections": 1,
"rowsRead": 0,

}
},

}
}
],
"dataConsistencyVerification": {

}
}

Any ideas on how I should proceed? It is the BasicDataSet_v0.ConferenceRoomCalendar_v0 I am trying to get from Graph. My first thought was to check if the dataset in Graph is even populated to begin with. Any idea on how to do that?
