Sempre esqueço, aqui está como inicializar uma subloja do mobx, e os dados correspondem ao conteúdo acima

export default class PurchaseOrderStore implements PurchaseOrderStoreModel { 

      shopMessageStore: any = {};


      constructor(rootStore: RootStoreModel) {
                makeObservable(this, { 
                        shopMessageStore: observable
                        setShopMessageStore: action.bound,

            }
             
        
      }
