how to define a model with arbitrary properties

[dodoto]

I want to define a model with arbitrary properties. And properties and values are typeof string.

[dodoto]

const TestModel = types.refinement(
  types.map(types.string),
  (value) => Object.keys(value).every((key) =>
    typeof key === "string" && typeof value[key] === "string"
  })
)
