How to use the ngrx-forms.updateRecursive function in ngrx-forms

export function formStateReducer(state = INITIAL_STATE, a: BlockUIAction | UnblockUIAction) {
  state = formGroupReducer(state, a);

  switch (a.type) {
    case BlockUIAction.TYPE: {
      state = updateRecursive(
        state,
        s => setUserDefinedProperty(s, 'wasDisabled', s.isDisabled),
      );
      return disable(state);
    }

    case UnblockUIAction.TYPE: {
      state = enable(state);
      return updateRecursive(
        state,
        s => s.userDefinedProperties.wasDisabled ? disable(s) : s,
      );
    }

    default: {
      return state;
    }
  }
}
