I'm new to javascript and I'm following this code but when starting automation it doesn't slide down page. (mobile)

    `$(FORMS_ICON_HOME_SCREEN).click()
    const {height} = driver.getWindowSize()
    const anchorPercentage = 50
    const startPointPercentage = 90
    const endPointPercentage = 10

    const anchor = height * anchorPercentage / 100
    const startPoint = height * startPointPercentage / 100
    const endPoint = height * endPointPercentage / 100

    await $(FORM_HEADER_TEXT).click()
    driver.touchPerform([
        {
            action: 'press',
            options: {
                x: anchor,
                y: startPoint
            }
        },
        {
            action: 'wait',
            options: {
                ms: 1000
            }
        },
        {
            action: 'moveTo',
            options: {
                x: anchor,
                y: endPoint
            }
        },
        {
            action: 'release',
            options: {}
        }
    ])
    await $(ACTIVE_BUTTON).click()
   });
  });

` As I'm starting, putting as much detail as possible, please. Thank u
