Tooltip from WeChat that should be from the system tray

System is running Ubuntu 20.04 LTS.
Kernel version is 5.4.0-125-generic.
Desktop environment is Unity 7.5.0.
Hardware is Dell Inspiron 7577, which has an Intel(R) Core(TM) i5-7300HQ CPU
and a Nvidia GTX 1060 Max-Q GPU.

When running an application that minimizes to the system tray when closed, the
application is effectively gone. There is no small system tray panel on the
screen, unlike what I see about the issue online. Maybe the system tray is size
0x0 on the top left corner, since the tooltip pop-ups that should appear on the
system tray icon appear on the top left of my screen.

The lack of system tray was observed with WeChat, I don't know of other
applications that use the system tray and have an automatic tooltip at the
moment, though if you point me to an installer I can try it to see if the
problem is reproduced.

Let me know if other information is needed.
