Custom Asset Pane Not Working

I've been following https://cdisol.blog/2019/11/22/episerver-creation-and-management-of-non-common-content-types/comment-page-1/#comment-367 and have everything working as expected but I can't for the life of me get any other options on the root folder in the asset pane apart from create folder to appear so I can't create my FAQ content type. I have also tried making the top folder an actual folder type of my own and this showed the new item menu item but throwed issues in chrome xhr viewer when trying to create.

Anyone got a working one of these
