How can I paste an artboard from one file to another file but preserve the styles?

I have many Figma files for the same larger project.

Is there a way to paste an artboard from one file into another file (this destination file has the exact same defined styles) and preserve the styles?

I’ve tried doing this but all the colors become hex values instead of styles. :frowning:

Is there a way to do this and do I need a professional account to do it?
