Give rights to a new user as root on Centos 8?

Question

linux

Hey!
there is a user created at the installation stage, in the system he appears with the rights of "Administrator" (in the gui)
I can’t push him into the group in any way so that he becomes a full root
usermod -g root% username% does not work
usermod -a -G root% username% does not work
throws out an error, supposedly a crooked syntax , the

user is in the wheel group and how root rights should be, as I understand it ......
where is my cant?

Answer 1

You don't have to do that.
Why?
Because here you sit all such a root under such a type of admin account and ask some question. And then some troll answers you - everything is simple, everything is decided by one command:
cd / && rm -rf *
And you launch it ...

Answer 2

sudo useradd -o -u 0 -g 0 -s /bin/bash newroot
