📚 Description

I tried the guest middleware, it did not work (n redirect, no unauthenticatedOnly behaviour). Added the missing snippet, everything works like a charm. I think has been missed in the docs. You can try for yourself.

I suggested this in an issue before but Zoey said this is expected when turning off the global middleware (You don't need to add this line if global middleware is enabled). Maybe a hint that this line is needed only when disabling global middleware would be best?

Works for me! Adding the value will not hurt in any case, but as you pointed out, could help reduce confusion. Thanks for making the adjustment ❤️
