findPopoverContent: (...args) => {
    const { element, selector, options } = parseQueryArguments(...args)
    return PopoverLocator.findContent(element, selector, {
      ...options,
      customMethods: {
        ...options.customMethods,
        ...customMethods
      }
    })
  }

    return content ? DatePickerLocator.find(content.getDOMNode()) : null
  }
})
