How can I do a God-tier url rewrite?

I'm using httpd on centos8, and I would like to put this rewrite into httpd.conf if possible!

I would like to make it so that a url like this:

www.mydomain.com/12345

gets rewritten as:

www.mydomain.com/folder/page.php?param=12345

I keep taking stabs at it and failing. Can the good people of stackoverflow help me out?
