Not able to connect to my local Git repo

Hi,

I am trying to connect to my local git repo referring to the blog @ https://blog.postman.com/syncing-your-openapi-raml-and-graphql-schema-to-github-with-postman/

However it doesn’t connect! Also it doesn’t asks for the url of my local git location! Does this works only with GitHub.com?

Regards,
Monish
