I was trying to create a new cms block plugin, and did everything according to the instructions described here&nbsp;[https://docs.shopware.com/en/shopware-platform-dev-en/how-to/custom-cms-block](https://docs.shopware.com/en/shopware-platform-dev-en/how-to/custom-cms-block)

However the element is never created. I think it has to do something with the src/public/administration/custom-cms-block.js file. Does it register something? How to create it for my own blocks ?
