sen2cor 2.9 plugin in SNAP?

I have installed sen2cor v2.9 on an Ubuntu 18.04 system.
The installation was successful - I can run sen2cor from the command line.
I’d rather run it through SNAP using the sen2cor plugin (which is SEN2COR280).
When I try to use it, nothing happens.
Is this because the plugin needs to updated, or because there is a missing step in the installation?

It seems like the v2.9 plugin in not available yet
