StickCPlus2 LCD backlight dimming?

[teastain]

I have a new StickCPlus2 that I want to dim or turn off the display backlight.
The old StickCPlus breathe does not work of course because the power system is very different.
I see that the schematic and the pin map say Output 27 is TFT_BL, but I cannot get either On or Off to turn off the backlight.
What am I doing wrong!!??
Thanks, Terry

Hello @teastain

M5.Lcd.setBrightness() works for me.

Thanks
