Branching help - main file updates not reflecting in branch

Hi all,

I am working on updating my design system by creating color and typography updates in the branch while continuing to add new components to the main file. Since you can’t publish a branch, I need to add them to the main file so that I can use publish and use them in other projects.

The new components aren’t showing up in the branch - is there a way to sync just this but not everything?
