Adding panels and controls to document settings tab – now possible?

[Przemek]

Hello Zac,

is there an official method of adding custom panels (settings, meta boxes) to edit post sidebar in Gutenberg? I mean document settings in “Document” tab.
Not all post meta are content-related and the sidebar seems to be a natural place for those.

Recently Yoast SEO announced their new sidebar (https://yoast.com/yoast-seo-8-0-introducing-the-yoast-seo-gutenberg-sidebar-a-revamped-meta-box/),
but I couldn’t find any tutorial or documentation on how to develop similar things.

Yes there is. I’ll be covering it in an advanced Gutenberg course later this year. Not sure I’ve seen any tutorials on it yet either.
