Is there a way of inheriting from

UmbSectionDefaultElement

it does everything. Also with menu items how do we do multiple items that point to the same apps with different ids?

Can you try using

class Mything extends UmbSectionDefaultElement

TypeScript through a wobble and couldnt find the element 😭

Source code diving it is and see if and how they reuse it in the codebase ?

Yeah I'll have to take a deeper look 🤞
