Understanding Webflow Edit Mode vs. Legacy Editor for Clients

Hello, I have a general question about Webflow Edit Mode and how clients can use it compared to the Legacy Editor. I currently direct all my clients to the Legacy Editor for their websites, but I’d like to have them use Edit Mode instead. My struggle is that I’m not sure how it works. From what I understand, you need either a Grow Plan or an Agency account for clients to use Edit Mode, and they also need to have their own Webflow account, let's say a general content editor. This is different from the Legacy Editor, where you could invite clients up to 3 on a CMS plan without them needing a Webflow account. Is that correct?
