Error while invoking the module from Cloudshell in AZ Portal /Documentation

[MDO78]

I experience an error while invoking the module from AZPortal CloudShell in PWSH mode - installing was easy going, invoking reports the error to open a web
Invoke-ZTAssessment: Unable to open a web page using xdg-open, gnome-open, kfmclient or wslview tools. See inner exception for details. Possible causes for this error are: tools are not installed or they cannot open a URL. Make sure you can open a web page by invoking from a terminal: xdg-open https://www.bing.com

What else do I need? Another module?
I would also appreciate some more documentation on the P0 P1 reference..

Thanks
