Lamp Two Led Strips: RGB + WW-CW Tuya CBU [BK7231N] Tuya OUT!!! la-rc24w12

Hi all, I would like to replace the software in the Ceiling Lap Chip Tuya CBU and there sits the BK7231N already flashed by esteemed colleagues. From what I've mapped the outputs 8 to 12 go directly to transistors Q1-Q5 and then on to the LED strips. so I suspect there will be no problems with the output. I would like advice on which RX-TX to connect to TX1 or TX2? Will the standard OpenBeken software on the BK7231N fit? Can it be done without soldering the circuit? If it comes to the access on the right side from the capacitors I can manage I will be grateful for advice. enclosed are photos and description of the leads.
