Rail with hidden pagination arrows

[ilgianfra]

Hello,

I wanted to create a rail of images which are a tags. I have created a custom arrows navigation and hidden them by default. I change the display to block when the user hovers on the rail
&:hover .splide__arrow--next { display: block; }

But now I am struggling when I start navigation with the tab and focus-visible, somehow I should put the display block on the arrow when the user has the focus on the rail.

Any suggestion?
thanks!
