External oAuth for bot/message extension app

[XDeveloper29]

I have created a bot/message extension app using teams toolkit in visual studio code in typescript language. I want to add authentication using oauth for GitHub. 
I have check a doc but it seems to be for a tab app.
https://learn.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/authentication/auth-oauth-prov...

Please help on how I can do oAuth authentication for the Github provider for bot/msg extension app then use the GitHub APIs.....
