chrome token signing Extension(using smartCard Readre Gemalto)

[guesmi 0]

I am trying to make an extension that will communicate with a native messaging host chrome-token-signing (https://github.com/open-eid/chrome-token-signing).I use gemalto smart card reader . I installed extension , it return an cmd window when I exit or put any string . I have message log TEST: ERROR {"message":"Error when communicating with the native messaging host."} Do I need to do Something I have installed the host in the registry like HKEY_LOCAL_MACHINE\software\Google\Chrome\NativeMessagingHosts\ee.ria.esteid and value C:\Users\dev\Desktop\chrome-token-signing\host-windows\ee.ria.esteid.json
The native application manifest.json:

{
 "name": "ee.ria.esteid",
 "description": "Give signatures with your eID on the web",
 "path": "chrome-token-signing.exe",
 "type": "stdio",
 "allowed_origins": [
"chrome-extension://ckjefchnfjhjfedoccjbhjpbncimppeg/"
]
 }   

manifest.json of extension {

Since this is an ESET forum intended for discussing ESET's products and malware and security issues and your query seems to be unrelated to ESET products, I would strongly recommend asking users in another more appropriate forum.
