Can't start the multibootusb aplication in GUI on Kali WSL2

[martin15560]

Environment

Windows: Windows 10 Version 2004 Build 20262.1010
Your Distribution version: Kali 2020.4
WSL2

Steps to reproduce

sudo apt-get install python3-pyqt5 p7zip-full parted util-linux python3-pyudev mtools python3-dbus python3-six

Then I downloaded the multibootusb from https://codeload.github.com/mbusb/multibootusb/zip/master and I extracted the archive and run:

sudo python3 ./multibootusb

After that I get following error:

Using python version  3.8.6 (default, Sep 25 2020, 09:36:53)
[GCC 10.2.0] on platform Linux-4.19.128-microsoft-standard-x86_64-with-glibc2.29
Running multibootusb version 9.3.0 from source...
Starting multibootusb GUI...
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.

Aborted

Can you please give me some advice how to run the GUI, thank you.

Edit: After strace sudo python3 ./multibootusb I got:
