BLE DTM with Zephyr project SDK 2.7.0

I like to use the DTM mode in a test mode of our device based on nRF5340. Using SDK 2.7.0 with Zephyr. Started with using the DTM example but it does not build. Beyond other errors

NRF_RADIO_Type

is not defined.

How can I use DTM on nRF5340 with Zephyr / SDK 2.7.0
