[Documentation of Material Configurations]

Currently, the only printer capable of showing Material Configurations UI is the Ultimaker S5, having a documentation would allow developers, as me, to implement it for any other printer. Does anybody knows if there is a documentation of this?

 

What is the object returned when the S5 is added from the cloud enabling the material configurations?

E.j.:
{printer : {id, model}
materials : [{id}, {id}]}
