Updating manifest from V2 to V3

This issue had already been addressed and ticked in Issue 21 but for some reason when I cloned it , manifest file had no changes in relation to V3. So I updated the manifest from V2 to V3. I used the extension-manifest-converter , you can check out the repo here : extension-manifest-converter .

The converter seems to follow all the protocols mentioned in Update Manifest but I couldn't wrap my head around background scripts so I just let them be:

Manifest V2

"background": {
    "scripts": [
        "lib/browser-polyfill.min.js",
        "lib/jquery.min.js",
        "lib/banana-i18n.js",
        "background-script.js"
    ]
},

Manifest V3

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

this resulted in making of another directory which had service_worker.js, but it was empty, so I let background scripts remain the same.
