Gcode for Chamber Fans and LED Light

Is there any Gcode where i can set the Chamber fans ? I dont want to use the temperature feature. Same for the LED lights?

RE:

I understand that the fan in the XL enclosure is controlled via the regular M106 command [ https://marlinfw.org/docs/gcode/M106.html ] with fan index 3. Didn't see a specific reference to the Core One in the respective source code on the Prusa Github, so I would assume it's the same.

For the chamber lights, it's probably M355 [ https://marlinfw.org/docs/gcode/M355.html ] and for the colored LED bar M150 [ https://marlinfw.org/docs/gcode/M150.html ]
