Local Tuya - adding a new device

With a LOT of effort I’ve finally managed to get Local Tuya operational, with my 4 light bulbs (Globe…but they’re apparently Tuya!). All good and fine and they are integrated nicely and grouped appropriately in HA. Strange process indeed.

Now, if I add more Tuya devices, is there no way for HA to pick them up automagically? Do I need to maintain both Tuya App (iOS) and Tuya IoT (web) as active so I can grab the keys?

While the “local” part appeals…the “China is watching” part does not.
