How can run onlyoffice in debug mode in my debian?

In my win10, add flag “–ascdesktop-support-debug-info” in property of DesktopEditors’ shortcut,it can run in debug mode on win10.
Now i want to run in debug mode in debian.
Method 1:
According to the manual “Running in debug mode on Linux | ONLYOFFICE”:

"/opt/onlyoffice/desktopeditors/DesktopEditors" --ascdesktop-support-debug-info

The error info:

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.
Reinstalling the application may fix this problem.
Aborted

Method 2:
The default command in “/usr/share/applications/onlyoffice-desktopeditors.desktop” is as below

Exec=/usr/bin/onlyoffice-desktopeditors %U

Execute in console:
/usr/bin/onlyoffice-desktopeditors --ascdesktop-support-debug-info
The error info:

(DesktopEditors:40263): Gtk-WARNING **: 11:39:41.609: Error setting gtk-cursor-theme-size in /home/debian/.config/gtk-3.0/settings.ini: Key file contains key “gtk-cursor-theme-size” in group “Settings” which has a value that cannot be interpreted.

Hello @withonly

Did you install Desktop Editors as a DEB package?

sudo dpkg -l   onlyoffice-desktopeditors

Thank you. Please try desktopeditors --ascdesktop-support-debug-info only, it should work.
