Hello, we’ve recorded a flashing guide for you:
This is a step by step video guide how to flash those new Tuya modules, in this case it’s WB3S/BK7231T but for other BK’s process is very similiar. The video shows flashing of 2gang wall switch and includes the “blocked UART lines trick” (temporary desoldering buttons controller chip that was interfering with RX/TX with easy desoldering method).
Process is very similiar to ESP8266, but the firmware flashed is OpenBeken - a multiplatform IoT firmware supporting BK7231T, BK7231N, BL602, W800/W801, W600,W601 and XR809 and soon more…

You can find more information about HA autodiscovery and configuration of OBK devices there. Have fun flashing!
