Gnatt plugin

Hello,

I am new to Quickbase .I am trying to explore the new Gantt plugin .I am using the trial version.I installed the Quickbase Gantt Template App from the exchange and the permission to install plugins for all admin is turned on. Still in the app settings under plugins the install option is not visible. What am i missing? ,is it that it is not available in trial version of Quickbase?

Thank you
