GitHub Card to a specific Branch

[NikarashiHatsu]

Is your feature request related to a problem? Please describe.
At this point, we have the GitHub Card Shortcode that refer to a repository, but I do really want the feature to be extended to a specific branch / tags.

Describe the solution you'd like
Using the GitHub API https://api.github.com/repos/username/repository/branches/branch should be enough. But since the API itself didn't provide the same key-value as the https://api.github.com/repos/username/repository, it might need both Requests to be send at the same time.

Describe alternatives you've considered
At this point, I gave my audience the exact link to the repository. It works, but less style makes it so dull and bland.

Additional context
None
