Unable to access received http code 407 github desktop

I have setup the Github Desktop version, we are using firewall and proxy in our office. I need to know how can i configure the proxy in GITHUB desktop application.

Thanks in Advance

You can configure GitHub Desktop to work with a proxy by running the following command from the command line (you will need to install Git for Windows if you have not already):

git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080

Replace proxyuser with your proxy username and proxypwd with your proxy password. Also, proxy.server.com:8080 needs to point to the URL of your proxy server.

Let me know if you run into any issues getting this working!
