Problem with Wickr in Whonix

I have installed Wickrme as it is dscribed on this website:

whonix . org/wiki/Wickr

The first Problem is when i try to start with the command :
$ Wickrme

bash: wickrme: command not found

but i can start it with:

$ snap run wickrme

Everything looks fine i can log in. I can navigate triugh the menue but i can t write new messages or find other users. If i try the screen goes complete grey.

The Terminal shows the following error message:

[0807/155653.945935:WARNING:resource_bundle_qt.cpp(116)] locale_file_path.empty() for locale Qt WebEngine ICU data not found at /opt/qt512/resources. Trying parent directory...

Reboot required?

No idea. Please contact upstream (original developers of Wickr) as per Free_Support_Principle.
