How to debug lombok objects

Does anyone know how to set a breakpoint in the following Person.toString() when using Eclipse or IntelliJ IDEA?

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.ToString;

@ToString
@AllArgsConstructor
@Data
public class Person {
    private String lastName;
    private String firstName;
}

EDIT:

If possible, I want to stop only when toString() is called.
