Tuya-Convert might not be possible for this device if the manufacturer started using newest Tuya firmware since this template was published. Instead you can likely serial flash Tasmota without soldering with a flashing jig, if the device is easily opened.
The original manufacturer code for the device is SM-SO306, which seems to be made by SHENZHEN XENON INDUSTRIAL LTD. These are usually Tuya software devices, sold under different brand names and logos in various parts of the world. I flashed Tasmota using Tuya convert (OTA) on a Wipro branded strip. Some devices I have identified to have similar properties are also listed below (all found in Amazon India website).
Known in various names, such as SM-SO306-U2 / SM-SO306-UZ2, Xergy Smart Power Strip, Wipro Smart Extension (DSE1150 in India) or Nishica Smart Power Extension (SM-SO306-2A)
