Is there any way to grant access to JavaScript browser API like tabs: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Browser_support_for_JavaScript_APIs#tabs for safari app extension? For web extension it is done in manifest.json. But I can't find a way to do it for app extension.
JavaScript browser API
Safari App Extensions have a different API to interact with windows and tabs. See:
