When posting in an open group on Facebook, how can you make it so your comments in the group don't show up on your feed for your friends to see?

Someone just posted a question in a group I’m in. They are asking how they can make it so their posts don’t show up on their feed, for their friends to be notified of the post. They understand that the group is “open” so anybody who goes to it can view any posts, but they don’t want their comments to show up on their feed for their friends to be notified of.

This is a good question, which is why I am wondering it, too.

In this case, it’s not anything secret, it’s just a baking group, but I don’t necessarily like the idea of every comment I make showing up in my ticker.
