Published Site - How Are Database Connections Updated?

My local setup is with wamp, as my Windows 10 laptop does not support Docker Desktop.

I’ve Published my site to a remote server, and all the PHP files have arrived safely. But I assume that my Database Connection server action steps are still pointing to my local mysql server.

How can I have those automatically update to point to the remote mysql database when I publish the site?

Best wishes,

Antony.
