I am trying to integrate our FreshDesk application with GitHub, using the app described here: https://support.freshdesk.com/support/solutions/articles/214680-the-github-app
However, when I go to the “Add More Apps” page and search for “GitHub”, the app in that article does not show up. I only see third-party GitHub apps that require separate accounts with their developers, not native FreshDesk apps.
How can I find and install the app described in https://support.freshdesk.com/support/solutions/articles/214680-the-github-app ?
