Flashing Saudio Bulb with Tasmota

Has anyone flashed Tasmota to a Saudio RGB bulb using a FTDI adapter? I don’t have a rpi to do the OTA method. I can get to the top of the board but the only the ground and VCC solder pads are labeled. Does anyone know the pinout of the 6 pin chip in the middle of the board? Or a way to expose the insides of the bulb? The board is glued into the base of the bulb.
