Connect Domain to Replit App

I already have full access to my domain’s DNS panel and an AI-driven app running smoothly on Replit under its default *.repl.co address. What I need is a clear, fool-proof path to point my custom domain to that Replit instance so visitors reach the app via https://mydomain.com (with SSL working)...
