Using trait on non-user model - GuardDoesNotMatch Exception

[ShareghYusefi]

I have a model that needs access to roles and found #310 as a potential way of implementing this feature. However, I'm receiving the following exception:

Spatie\Permission\Exceptions\GuardDoesNotMatch
The given role or permission should use guard `` instead of ``.

Is this workaround no longer being supported?
