roundcube toolbox 1.4.10 installed successfully but not working?

[skecher]

Hi there, I'm new here ... have run RC for years ...

I installed roundcube-toolbox primarily for forwarding/vacation messaging (I could only find this plugin, are there others?)

https://github.com/gianlucagiacometti/roundcube-toolbox/releases/tag/1.4.10

There are no obvious errors, no logged errors either.

I don't find anything that would allow me to forward emails when logged in to RC.

How is it intended to work?

Many Thanks, Caesar.
