How to access default context menu item of your chrome extension?

I was wondering how you would access the default context menu item for your chrome extension (which is greyed out in my case) which I want to use to redirect to my chrome:extension page onclick.

background.js

chrome.contextMenus.onClicked.addListener((info, tab) => {
    if (info.menuItemId === 'MONEN') {

        console.log('My context menu item was clicked!');
    }
});

manifest.json

...
"background": {
    "service_worker": "background.js"
}, ...
