Fails to add Custom domain and subdomain to appwrite sites and functions

Case 1 : I've a domain ("remiel.work") which i want to host my portfolio thru appwrite sites. when i try to connect my domain (which i bought from spaceship, managing DNS records using cloudfare) to the sites, it tells me to update the nameservers (why can't i just add any DNS records for verification instead of nameservers??), i tried to change the nameservers in spaceship, 2 nameservers from cloudfare and 2 from appwrite now, still even after 24 Hours, the domain isn't connected. it would be helpful if i can just verify and connect my domain to the sites with just adding DNS records instead of changing my whole nameservers. (had to go back to vercel for hosting my portfolio 🥲)

Case 2 : I created appwrite functions to serve as a backend for one fof my projects, it worked well. but i wanted to connect my subdomain ("api.remiel.work") to that function, when i add them and verify them by adding the required CNAME to the DNS Records (i use cloudfare), it doesnt work. with that, my root domain is getting added in that organization domains ("remiel.work") which i dont want to happen. i just want to add my subdomain (verify only with DNS Records instead of Nameservers) to my appwrite functions and i didnt want it to add the root domain to the organization when i do this
