Custom Cms Block Doesn't Appear on Storefront

I’m trying to create a custom CMS block to change a Shopware original block.
Everything works up to the point where I add the block to the page using Shopping Experiences Editor.
But when I go to the page where I added the block on the Storefront, nothing loads where the block was supposed to be. It’s as if the block isn’t even being initiated because I’ve put logs on the createdComponent method and nothing shows up.
Does anyone have any idea of what can be happening?

TLDR: Custom block shows up on Shopping Experience, but nothing appears on the storefront

Did you add a twig file in views/storefront/…?
