How cool is that?

And we can do this very easily. We simply need to change our code from:

<PluginDocumentSettingPanel name="my-data" title="My Data">
	<TextControl value={myData} onChange={setMyData} />

To this:

	<PluginSidebarMoreMenuItem target={sidebarName}>
		{ sidebarLabel }
	<PluginSidebar name={sidebarName} title={ sidebarLabel }>
			<TextControl value={myData} onChange={setMyData} />

So, basically we simply change the wrapper from PluginDocumentSettingPanel to PluginSidebar.
