Add left arrow and right arrow to the slideshow image (Dawn Theme)

[dreamtechzone_5]

Hello Everyone!
I am using the Shopify Dawn theme. I want to add left arrow and right arrow to the slideshow image in mobile and desktop mode. I want to add hover effect to arrow. I would like to keep the navigation bar as it is. Also, want to remove the Pagination style (marked in yellow). Is it possible? Thank you.
