Hi, I have two questions that I need your help with！

1：When I create a new page with Elementor, how can I add a side product filter? How can I customize the content of each category filter? Do I need to download another plugin? I hope you understand what I mean – -!
2：For example, I use the Furniture 2 theme, but I don’t like the shop page of this theme. I want to change it to another custom shop page. How can I change it? There are so many templates. How can I use them?
