Sharing a report including the dataset GA4

Hi, 

I have created a report in Looker Studio and connected the GA4 dataset. This all worked and I can see the data as normal.
Now I would like to share the report with a colleague who does not have access to Google Analytics. She has signed in with her Google account and I have shared the report with her using this email address. However, when she opens the report, it says that no connection to the dataset can be established. The error message appears: fc7a44c6
What could be the reason for this?
I have already tried creating an extra data source in Looker Studio and sharing it with her, but that didn't change anything.
I would be very grateful for any help.
