Remove a SharePoint Group from a Folder

Good morning. Here's an example to illustrate my question. I have a document library named HR. In that document library, I have a folder named Benefits. A group named currEmployees has read access to the folder named Benefits. How would I remove currEmployees' access to Benefits?

I am asking how to remove a SharePoint group from a SharePoint folder. I have found examples that explain how to remove a group from a list -- but I need to remove a group from afolder within a list. Thanks in advance.
