const createFrozenAtom = freezeAtomCreator(atom)
const objAtom = createFrozenAtom({ count: 0 })

Instead of create a frozen atom from an existing atom, freezeAtomCreator takes an atom creator function and returns a new function. You can use this not only for atom, but also for other atomWith* creators such as atomWithReduer.
