What does it take for a Tuya device to be discoverable?

I bought a T34 Smart Plug. After some gymnastics I added it to SmartLife and it shows up in my Tuya IoT Cloud project (together with a switch I installed back in Dec 2021).

In localtuya I have the cloud account configured and see the switch (which was already there for 5 years, and it is autodiscovered).

I however do not see the plug as autodiscovered. It is live on my network (and live in the iot platform).
What did it take for a Tuta device to be autodiscoverable in such scenario?
