Raspberry PI 5 + Razberry2 (Z-WAVE RASPBERRY PI BOARD, "RPI RAZBERRY2")

Hi,
First of all this is all new to me so bear with me…

Im trying to get HASS 2024.1.5 (running on Raspberry PI 5) to get integrated with Razberry2 (Z-WAVE RASPBERRY PI BOARD, “RPI RAZBERRY2”).

If I choose settings/add integration and choose manufactor (z-wave.me) I get popup and should add url to server and API-token.

Can anyone explain to me what I should do next?
