Respeaker Mic Array V2 Control Each LED Pixel Not Working

Hi So basically been been tinkering around with the pixel ring for a while now… but I can’t seem to find how to create custom patterns or control single LEDs…

I See there’s function to control individual leds
Command 6 [r, g, b, 0] * 12 custom mode, set each LED to its own color. but it doesn’t seem to work for each pixel…

is there anything am missing here… ?
