Setting up cgroups with /etc/cgconfig.conf failed with Cgroup, requested group parameter does not exist

I'm looking at getting cgroups working on my linux machine and well it's been a pain. I feel like this should be a lot easier as resource management is pretty key to a healthy desktop environment which is why I'm trying to use it but I've just run into so many problems. I have a /etc/cgconfig.conf file that looks like this:

group "chromium_slack" {
    perm {
            admin {
                    uid = "nate";
                    gid = "nate";
            }
            task {
                    uid = "nate";
                    gid = "nate";
            }
    }
    cpu {
            shares="50";
    }
    memory {
            swappiness="60";
            limit_in_bytes="256000000";
    }
}

And when I start the cgconfig service with this:

sudo systemctl start cgconfig.service

I get a service status Cgroup, requested group parameter does not exist that looks like this:

× cgconfig.service - Control Group configuration service
     Loaded: loaded (/usr/lib/systemd/system/cgconfig.service; enabled; preset: disabled)
     Active: failed (Result: exit-code) since Thu 2022-12-15 15:17:16 EST; 11min ago

Dec 15 15:17:16 nx systemd: cgconfig.service: Failed with result 'exit-code'.
Dec 15 15:17:16 nx systemd: Failed to start Control Group configuration service.

But when I try to do this all manually with cgcreate like so:

sudo cgcreate -a $USER -g memory,cpu:chromium_slack
sudo echo 256M > /sys/fs/cgroup/chromium_slack/memory.limit_in_bytes

I get a permission denied: /sys/fs/cgroup/chromium_slack/memory.limit_in_bytes error. So I guess my question is... How the heck do I get this working?
