This slot allows for injecting items into the bottom of the pre-publish panel that appears to confirm publishing after the user clicks “Publish”.
Example
import { registerPlugin } from '@wordpress/plugins';
import { PluginPrePublishPanel } from '@wordpress/editor';
const PluginPrePublishPanelTest = () => (
<PluginPrePublishPanel>
<p>Pre Publish Panel</p>
</PluginPrePublishPanel>
);
registerPlugin( 'pre-publish-panel-test', {
render: PluginPrePublishPanelTest,
} );
