Install Chrome Extension from Mac App - macos

Question

want to install chrome extension when mac app is installed.
i followed the instructions on the developer site of chrome Other Deployment Options
Tried both the methods
Local file url
Created file external_extensions.json at path /Users/Sadiq/Library/Application Support/Google/Chrome/External Extensions with contents
{
"external_crx": "/home/share/extension.crx",
"external_version": "1.0"
}
But when i restarted chrome the extension at that path is not installed on chrome.
Store Installation:
Created file fhbjgbiflinjbdggehcddcbncdddomop.json at path
/Users/Sadiq/Library/Application Support/Google/Chrome/External Extensions
with contents
{
"fhbjgbiflinjbdggehcddcbncdddomop": {
"external_update_url": "http://test.com/extension_info.xml"
}
}
Created extension_info.xml file at hosting with following code
<?xml version='1.0' encoding='UTF-8'?>
<gupdate xmlns='http://www.google.com/update2/response' protocol='2.0'>
<app appid='fhbjgbiflinjbdggehcddcbncdddomop'>
<updatecheck codebase='https://clients2.googleusercontent.com/crx/blobs/QgAAAC6zw0qH2D JtnXe8Z7rUJP0d-cjv- 4fr0OfD1rZlXmwxm1zzQqbU1RRtbPRUspFh5VJIFInV7jQnzNI5Ax7-tVFFNKUqiQdoiA- 43Tdd46i1AMZSmuUS-XRXhbdPB5d5cMLUhLCthCuF7g/extension_1_0_0_26.crx' version='1.0.0.26' />

At first time it works but when i uninstall the extension and relaunch the browser it doesn't install it again.
This is intentional. When programmatically installed extension is uninstalled by the user, it becomes blacklisted and will not trigger installation again.
The user can still manually install it from the store, but there's nothing you can do if it was denied.
