Not all Tuya based products are integrated with ST. Click on the device tile in the Tuya based app of your choice, in the upper right corner click on the pencil or 3 dots. On the new page 3 party controllers should be listed. If SmartThings is listed you are good. If ST is not listed you will need to use the following work around. I would also suggest you try using the Tuya App since it works with all the Tuya based products which are many.
