We ran into issues setting up Remote Desktop on RHEL 10.1 headless, with this user doc.

1. The docs describe the procedure for a non-root user with sudo access. This is absolutely necessary. Running the setup as root user will fail. IMO it makes sense to mention this explicitly.
2. Other sections mention explicitly that the firewall has to be updated, this section should do that, too, IMO, that is, add a step to run

   # firewall-cmd --permanent --add-port=3389/tcp
