Changing responsive breakpoints in Flatsome theme

Hi, I am currently working on a site that has a couple of breakpoints which aren’t covered by the default Flatsome breakpoints. I have managed to add the custom breakpoints to the UI by creating an action in my functions.php but they don’t actually seem to have any effect on the pages. What’s the best way to add breakpoints?

Many thanks in advance.
