Yes it should be like this. Instead of word Tuesday I used Logout by mistake

The first code was taken from following link and it does not work, I
got error , I tried again

https://metacpan.org/pod/Dancer2::Manual#Writing-a-plugin

Then I found another link for plugins:

https://metacpan.org/pod/Dancer2::Plugins

At this link the example was simpler, and was about Logout. I applied
it to Tuesday example and while copying here I made a mistake

Regarding first code, I got error but perhaps I am using wrongly so it
is better to offer change it after being sure
