using ssh connect to a server, fail to start app. How to solve ?

my system is Archlinux, and using gnome.
I use ssh to connect to my school's server. Because I want to use the lumerical in my school's server (I don't have this application on my own labtop).
Now through ssh command, I succeed in connecting my account. I can see all the files. But when I tried to launcher Lumerical, it warn me:

```
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Abandon (core dumped)
```

Is there anyone can help me to solve this problem?

Use X forwarding, if supported.

ssh -Y ...

PS: And don't crosspost.

I'm sorry for crossposting. I don't know this problem belongs to which part.

Use X forwarding, if supported.
