Issue with mutable schema properties and object construction in Effect Typescript library

const MySchema = Schema.Struct({
  identifier: Schema.NonEmptyString,
  args: Schema.mutable(Schema.Array(Schema.Unknown)),
}),

 const MySchema = Schema.mutable(
  Schema.Struct({
    identifier: Schema.NonEmptyString,
    args: Schema.Array(Schema.Unknown),
  }),
);
