Silly Q reg Atom & Github


Am a Newbie to this, am using Atom 1.25.
Have a github repo which I fully replicated. All good.
My issue is that I added new branches to the Github Repo through other applications. I don’t see them in Atom. Fetching doesn’t help, pulling doesn’t help.

How can I get these other branches which show on Github to also show in Atom, so that I can consolidate the code?

Thanks for insights.
