How to check a folder entry on click?

[krotalias]

I created a folder for a r3f project. I would like to check the model "part" that have been clicked on:

const [config, set, get] = useControls(() => ({
parts: folder(
{
gear: false,
shaft: false,
cylinder: false,
piston1: true,
piston2: false,
piston3: false,
},
{ collapsed: true },
),
all: false,
}))
return (
<group
onClick={(e) => {
const part = e.object.parent.name
hover(part)
let value = get(part)
set({ ??????? }). <--------------
}}
........

However, no matter what I try, I Always get:

ERROR
mappedPaths[p] is undefined

Any clue wold be welcome.

Thanks.
