Make A-Name record use a domain for IPv4

So I use a service called hopto,org that basically updates my IPv4 address automatically because my IP is dynamic. I basically just need to look up example,hopto,org and voilà my ipv4. What I want to do is take that domain and use it with an A-Name record and create https links like example,mydomain,cyz .

I am currently running a homelab Debian server and using NGINX Proxy Manager within a Docker (Portainer).

Technically everything works but I would need to manually change the IPv4 every second day and I don’t know how to make it static with the Hopto service or the cloudflare API.

Could I make a CNAME record that directs to example,Hopto,org and then my A-Name that directs to local host?
