Need help on Oauth-2.0 Token with Nginx reverse proxy

[blason]

Hi Folks,

I am trying to setup a reverse proxy on nginx with server at backend and
from HAR file I understand it uses Oauth-Token-2.0 with POST method.

However I am unable to set the stuff and seeking help here.

My original server here is assuming

https://test.example.net:9084
And for Outh from har file I can see the request goes to
https://test.example.net:99/connect/token

Here is my config
