Chrome.usb is now api for chrome app or extension? - google-chrome-extension

I found the api in chrome extension docs which reads the api is deprecated chrome app platform. Does this mean the api is accessible for chrome extension now? However, it seems something goes wrong when I take it as an extension api.

There is a currently experimental API. https://developer.mozilla.org/en-US/docs/Web/API/USB

Chrome extensions: is native messaging deprecated?

When navigating to "native massaging" documentation, first thing you see is a warning:
Important: Chrome will be removing support for Chrome Apps on all
platforms. Chrome browser and the Chrome Web Store will continue to
support extensions. Read the announcement and learn more about
migrating your app.
Since all this documentation located under Chrome Apps docs, is it means that "native messaging" feature going away as well? If it is, what is the alternative for communicating with chrome extension from the outside?

Postman application- extension from chrome is written in which language?

Get list of Chrome extensions from Chrome app

I have a Chrome extension that uses the chrome.management API to get a list of installed Chrome extensions and apps. The problem starts because I also want to use the chrome.syncFileSystem API which only seems to be available to Chrome apps.
If I switch the extension to an app, I can no longer use the chrome.management API. I haven't been able to find an API to access the installed extensions from an app. Any tips?
I don't think you can, not without having both an extension and an app.
Google has a private API to do that, but for public API, they want apps to be as independent as possible from the browser.

How integrate chrome application with extension?

I'm writing an extension.
A part of this extension contains an html page.
I'd call that page, also as a Google Apps,
inserting an icon between applications of chrome.
It's possible create a manifest file to integrate the chrome app with chrome extension?
No. You'd create both an app an an extension, then encourage the user to install both if you detected that one wasn't installed.
There is an outstanding feature request to allow bundled installations of multiple apps/extensions.

I'm really confused about Chrome Extension+Google API

I'm really confused. I want to make a Chrome Extension that can update a user's Google Calendar, what kind of program should I register under Google API?
Is it Web App? But I don't plan to have a server to host anything because Chrome Extensions are in the browser itself.
I really don't think it's a service account, but if it is, somebody enlighten me!
So that leaves installed applications?
Well, Google Extensions and Google API are very different in nature, and they don't have a special way to comunicate themselves.
Chrome Extensions are javascript code running in the browser allowed by a Chrome user, with more rights than a normal page; while Google API is accessed by server code, just as Google Apps Scripts (javascript code running in a Google server with some Google user's right).
