Getting Relume Style Guide into Your Existing Webflow Site

Hello everyone, This is my first time using Relume and Webflow. I created a site in Webflow and purchased the Basic plan. Now, I’ve decided to use Relume and import my wireframe, but it says I need to get the Relume Style Guide. When I try to clone it, it creates a new website, which is on a free plan. How can I get the style guide into my existing website with the Basic plan? I would really appreciate your help. Thank You!
