Product image pop up arrows

-- HikaShop version -- : 4.1.0
-- Joomla version -- : 3.9.8
-- PHP version -- : 7.2

Hello,

the configuration for the pop up is this:

The problem is that in mobile screens its really hard to slide from o ne image to the other cause the arrow is very small.
Is there some other way to use arrows or slide the image when they pop up?

Thank you
