Bitbag CMS Products Association

Hello, I’m seeking for guidance and advice on how I should use the CMS plugin. I’m trying to display products according to their categories, I thought the ideal way to do it was to render blocks associated with the product’s category. I’m able to display the codes added in the block but the associated products don’t display. Please do reach out if you know how I could display the associated products in the block or if you have a better idea of how I would be able to display products according to their categories, thank you in advance!
