I'm sorry, but what do you actually need help with? Do you need help with enabling Cloudflare, disabling Cloudflare or just making your website reachable?
From my end, swaglertools.cf is working and is using Cloudflare. If it doesn't work for you yet, note that enabling and disabling Cloudflare requires a DNS change. You don't need to configure anything for that yourself, but the changes can take up to 72 hours to become visible.
