Sanity check on LED circuit - WS2811, ESP32

Howdy people,

I'm trying to drive WS2811 LEDs with a Meanwell PWM-200-12 driver. I'll use WLED or FastLED probably.

I'm concerned that I'm using the red and white "power injection" leads incorrectly and I should be powering it all from the red, green and white cluster

I don't need the PWM dimming capability with of the driver as the WS2811 dimming is all digital anyway.

Also, how neccesary is the tie from ESP GND to OUT- on the Meanwell driver?

Thanks a bunch
