Custom Name for Formbuilder Reactive Form - Angular 7

Nowaday I´m creating this formBuilder:

 return this.fb.group(
      {
        myaccount: [ '', [Validators.required]]
        }
    );

When I´m getting the error message for element I´m doing:

Object.keys(formToValidate.controls).forEach(key => {

      const controlErrors: ValidationErrors = formToValidate.get(key).errors;
      if (controlErrors != null) {
        Object.keys(controlErrors).forEach(keyError => {
          if (keyError === 'required') {

            console.log('Key control: ' + key + ', keyError: ' + keyError + ', err value: ', controlErrors[keyError]);
          }

        });
      }
    });

Display: Key control: myaccount, keyError: required, err value: true

The problem is I dont want to display 'myaccount' but 'My Account'. I tried in some way to do this:

return this.fb.group(
      {
        myaccount: [ 'My Account','', [Validators.required]]
        }
    );

but this is not possible. How can I do this?

EDIT:

I want to display label (Specific one) and not the value on the form. I want to customize a specific name for my console.log?
