I'm writing a Python script and I want to auto-link a light mixer to multiple lights.
The manual process for this is just to click and drag a light from left to right (light list > attributes) and it links everything automatically. . In the parameters, everything has been filled out.

However, if you have a fresh light mixer without any existing links, the settings > layout section in the parameters doesn't exist

I'm not sure how to access these parameters, to then link. Can someone let me know how I can do this, or if there is an easier way to go about doing this?

Thanks
