How to use X-Http-Overriden-Method in Postman

I have a question from PostMan rather, it turns out that in my controller I have a GET request in which I have to send an @RequestBod, I have been asked to do a POST and with the method

@RestController
public class TestController {

    @GetMapping("/test")
    public ResponseEntity<Test> example (@RequestBody Test test){
        return new ResponseEntity<>(test, HttpStatus.OK);
    }
}

The Test model has only one attribute that is a String and is called a test.

public class Test {
    public String test;

    public Test(String test) {
        this.test = test;
    }

    public String getTest() {
        return test;
    }

    public void setTest(String test) {
        this.test = test;
    }
}

I would need to know how to send the RequestBody from Postman, now I do it like that.

Algua help?
