Failed to get the Z-Wave JS add-on info: Addon core_zwave_js does not exist

Can’t get Z-Wave network setup and I don’t know what is actually wrong, so any help would be much appreciated.

Plugged in a Zooz S2 stick (500 series) to my Pi running latest version of HA. Did the whole restart, clear cache thing to make sure everything was “clean”. The stick wasn’t automatically found, so I tried to install the Z-Wave JS integration.

The install failed because Failed to get the Z-Wave JS add-on info: Addon core_zwave_js does not exist. The log states that the source is components/zwave_js/config_flow.py:258

For what it’s worth, I have installed the ZWaveJS2MQTT add-on because the Z-Wave JS add-on doesn’t show up when I search in the add-on repo (https://addons.community).
