Fedora 35: virsh cannot detect RDPWindows

After installing the VM and configuring it, I tried running the `bin/winapps` command to test it, and I get this:
```
RDPWindows is not running, run:
virsh start RDPWindows
```
After running the afformentioned command:
```
error: failed to get domain 'RDPWindows'
```
I tried forcing it with `sudo` and it worked, so I tried running the installer.sh script (also with sudo), again with success, but now none of the apps will launch with this method.

Given that the instructions mentioned nothing of adding `sudo`, there must be a way to get `virsh` to detect the VM without `sudo`. I tried adding my account to the `kvm` and `libvirt` groups but to no avail.

Any help would be very much appreciated.

Start by reproducing the reported behavior as a non-root user with bin/winapps and virsh, then inspect how installer.sh configures the VM and how bin/winapps invokes virsh. Compare the user and sudo execution contexts; done means RDPWindows is detected and applications launch without sudo on Fedora 35.
