It doesn’t seem possible to add the prebuilt components into your own components?
If I want to add a “alert” for example into my component, it won’t do it and will only bring it in outside of the component I’ve built.
It looks like because they’re all built as sections, it’s restricted from being inside components.
This is very limiting as I don’t want to add an alert on every page individually when the point of a component is to make it reusable.
