I'm using libusb to read data from my ant+ dongle.
In zwift I see my current heartrate so that tells me that the dongle works.

In my code everything is connected but I do not receive any data packages.

Do I need to send a package to the dongle to start receiving?
If yes, what does this package look like?

There is a configuration sequence required to establish the rx channel. Please see the DEMO_HR_RECEIVER folder of the "ANT PC SDK" download and the "ANT Message Protocol and Usage" document for more details.

Are you trying to use zwift at the same time? The USB device will only be available to a single use at any given time, so you will need to close zwift, or use two dongles.
