'chrome extension force install outside Chrome Web Store

How to force install a self hosted chrome extension in my organization?

I went over the requirements detailed in the official documentation.

I have packed the extension with Chrome's "pack extension" button, hosting it in a publicly accessible location, headers are as required. The extension is very basic. Works when I load it (unpacked), when I manually download it, it shows "package is invalid, CRX proof required" which is fine, because it's not from the Web Store. To force deploy it I use the google admin panel (Adding the extension by ID from a custom URL)

Any further ideas?
