I'm having a hard time finding out exactly what MediaEmbedToolbar does and what toolbar items are available for enabling via the toolbar array. The documentation has no mentioning or examples, unlike the image toolbar.

Array.from( editor.ui.componentFactory.names() ) shows no items related it to it either other than the parent mediaEmbed button.

Hi, sorry for the late reply. MediaEmbedToolbar will most probably be used and properly documented when we introduce styles for media embed (keep in mind that we do not provide any ETA for this). There are also no default items/configs that can be used with it.
So currently it can serve as a base for custom development, if you for example would like to create a plugin with your own custom items.
