我正在尝试从这里运行代码https://github.com/vt4a2h/uml-tool我发现自己被这个错误信息困住了：
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: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.
我使用的是 Windows 10 和 WSL 2（Ubuntu 20.04.2 LTS）

我该怎么办？如何修复这个问题？
