To have the tray button immediately open the chat

Linux Mint 19.03 x64. RocketChat client rocketchat-3.8.2-linux-amd64.deb installed. The problem is that when you click on the tray icon - a menu appears with the choice of “Show” and “Exit”.

How can I make it so that clicking on the tray icon immediately opens the chat window? Thank you!

This MAY be a bug. In version 3.8.0 it listed this bug fix (below) but you are using a newer version so I am not sure if it is a new bug or not.
