Having difficulty with sequelize association methods.

Hey I am have a problem with the sequelize package. I am try to create an association between the two models 'User' and 'Cart'.

User.hasOne(Cart);
Cart.belongsTo(User);

User.hasOne(Cart);
Cart.belongsTo(User);

Now in my app.ts file i am try to create some dummy user and cart.

(async () => {
   try {
     await sequelize.sync({ force: true }); // Remove this line in production build.
     // await sequelize.sync();
 
     let user = await User.findByPk(1);
     if (!user) {
       user = await User.create({
         name: "TestSubject1",
         email: "[email protected]",
       });
     }
 
     console.log("User created:", user);
 
     let cart = await user.createCart();
     
     console.log("Cart created:", cart);

     app.listen(PORT, () => {
       console.log(`Server running at http://localhost:${PORT}`);
     });
   } catch (error) {
     console.error("Error during Sequalize sync or user creation:", error);
   }
 })();

(async () => {
   try {
     await sequelize.sync({ force: true }); // Remove this line in production build.
     // await sequelize.sync();
 
     let user = await User.findByPk(1);
     if (!user) {
       user = await User.create({
         name: "TestSubject1",
         email: "[email protected]",
       });
     }
 
     console.log("User created:", user);
 
     let cart = await user.createCart();
     
     console.log("Cart created:", cart);

     app.listen(PORT, () => {
       console.log(`Server running at http://localhost:${PORT}`);
     });
   } catch (error) {
     console.error("Error during Sequalize sync or user creation:", error);
   }
 })();

However, I am getting error stating "createCart" property does not exist on the type 'User'. I was expecting the hasOne or hasMany relation in sequelize to provide me with some special methods. Please correct me i am wrong and help me clearify my doubt.
