No white slider Gledopto GL-C-007S

Hi, I have a couple of the GL-C-007 S, RGBW, Gledopto LED controllers. Home assistant and Z2M. They connect fine and integrate with my setup. I can control the RGB colors. I do not have a slider for the white color. The only white I get is from mixing the RGBs (center of color wheel) but have not found a way to turn on white by itself. I tried edge but no success. As far as I know they only come in 1id. Is there a way to turn on and control the White color? Thanks for any insight.
