Understanding Relume's Features and Upgrade Requirements

Hello everyone. I'm new. A few days back, I was curious about Relume, so I created an account and built a quick test project. Today, I wanted to see the copy-and-paste function from Relume to Webflow, but I got a message that I had to upgrade to view the wireframe. Is that how it works? I mean, do I have to pay to see if it works for me?
