Show posts lists as grid on a page

I want to display my blog posts as a grid on a page (https://mdmoreno.com/press-sample/), but I can’t figure out how to make the template available. The only two templates under Page Attributes in the editor are “Default Template” and “Custom page Example.” I am using Customizr Pro on Modern. I am also using a child theme and I’ve copied the template folder from customizr-pro to customizr-child. I’ve read your documentation and I understand how to design the lists (https://docs.presscustomizr.com/article/160-designing-the-lists-of-posts-blog-archives-search-in-the-customizr-theme), I just don’t see how to activate the templates and use them on my pages. I’m still trying to learn PHP, so it’s a bit challenging for me to create my own template to accomplish what I want. I will appreciate any guidance.
