Describe the solution you'd like

As a User I would like to get messages when I visit otasoft website so that I can get notified about changes.

Create request to customer microservice that will return an array of user messages. Similarly to previous task, User ID can be passed as param or taken from JWT token (cookie).

1. Both REST controller and GraphQL query that will take the data from the client and send it to the service
2. API Gateway validation (DTO validation with Validation Pipe)
3. Send data to the microservice (customer)
4. Correct data flow is developed (controller -> service -> command -> command handler)
5. Array of customer messages is returned
6. In case of errors adequate exception is thrown

• If you have time and energy, you can develop "Remove message" functionality that will remove message from message array of a customer.
