Tuya/Zigbee device howto

Hello people,
obviasly I can not understand how Tuya work.
I bought this device :
Tuya Smart Zigbee Smoke Detector
but it is not suported by zigbee2mqtt.

I did try to configure with no succes and want to understand how can I use it.

In general - do I need tuya HUB , like zigbee hub (dongle) ?

devices as this zigbee/tuya - are they able to connect with no hub ?

Thank you in advance
