How to change cross-sell slider to 5 products

Hello, I’m using the cross-sell feature on the product page. It makes a slider by default and it shows 4 items and the rest is hidden by the slider, is it possible to change it to 5 products shown? I did find that it’s this file: 

 storefront/page/product-detail/cross-selling/tabs.html.twig which calls inside it for storefront/element/cms-element-product-slider.html.twig and that contains the following: sliderConfig: config. 


But I’m unsure where exactly to change it? Inside the variable? And where is that located?

Thanks in advance!
