Cannot execute sinkListItem method

[Kilovatiy]

I like to have ability to sink/lift list items from a bubble menu, so I add handlers like this:
sinkListItem() { this.editor.chain().focus().sinkListItem().run(); },
and
liftListItem() { debugger this.editor.chain().focus().liftListItem().run(); },
But it won't work. Can() method returns false as well.
However, pressing 'Tab' works as expected. What needs to be done in order to execute these methods (lift and sink).

I create an example here.
If I create bullet list and try to use a bubble menus,(it appears only on selected text), element 'sub-menu' it wont sink an item, however if i set the cursor to the beginning of a li and press 'tab' all work fine. May it be that selection somehow make commands break?
Thank you for your reply!

Instead of this.editor.chain().focus().sinkListItem().run() you have to call this.editor.chain().focus().sinkListItem('listItem').run().
