How to use the @uipath/angular/testing.Key.Escape function in @uipath/angular

it('should clear selection if Esc is pressed', () => {
            component.clearable = true;
            component.value = [faker.helpers.randomize(items)];

            fixture.detectChanges();

            expect(uiSuggest.value.length).toEqual(1);

            const display = fixture.debugElement.query(By.css('.display'));
            display.nativeElement.dispatchEvent(
                EventGenerator.keyUp(Key.Escape),
            );
            fixture.detectChanges();

            expect(uiSuggest.value.length).toEqual(0);
        });
    });
