Just trying to get basic gcc and g++ onto an rhel 10 vm

So i downloaded rhel 10, obtained a developer license, and registered the VM. but when i go to list repositories, none show up. as in, the list is entirely empty. Apparently, none are available. When i asked redhat's AI what the issue might be, it suggested that instead of openpool i should use something else. Unfortunately, after a very frustrating 15 minute conversation, i closed that window since not a single one of its commands or suggestions about how to operate subscription manager worked. not one. so.

How do i in fact get the basic repositories attached to this brand new rhel 10 vm, which is already registered as a developer?
