Mathieu C. not sure if this answers your question, but this is what tripped me up: After cloning the style guide, installing the Relume webflow app, then you go to your relume app in webflow and launch it from there to do the import. I hadn't used any apps before in webflow, so I could not for the life of me figure this out until I just CMD + E in webflow to find where the relume app went.
