Cloudflare use with SquareSpace

Has anyone used Cloudflare with their Squarespace domain before? I'm trying to connect my domain to Cloudflare so that I can use my subdomain on Kajabi and continue to run ads on Facebook.

Any help is great! I've been trying to follow both Kajabi's walkthrough and the vendor-specific DNS records on Cloudflare's website, but it's proving difficult since I don't have all of the corresponding DNS records that Cloudflare shows in their walkthrough.
