Minecraft pocket edition on Kubuntu

Apologise if I am posting in the wrong place, but I’m trying to install mcpe on kubuntu with snap as instructed in:

https://snapcraft.io/install/mcpe/kubuntu

When I run the game this error message shows up:

/snap/mcpe/5/usr/bin/mcpelauncher-ui-qt: error while loading shared libraries: libQt5WebEngineWidgets.so.5: cannot open sha
red object file: No such file or directory

I tried installing by other means but the issues become too dauntling for a noobie.
Any help is appreciated!
Thanks

how exactly do you run the app when this happens ?

By typing ‘mcpe’ on the terminal (no sudo).
