Lost Plasma5

While removing kwalletd5 with zypper I accidentally damaged Plasma5 by deleting some files that I thought only kwallet needed. Only IceWM is available to me now. Is there a simple way to restore Plasma5?Thanks for any advice.

Consult /var/log/zypp/history (or “Extra”->“Show History” in YaST, IIRC) regarding what has been uninstalled and install those packages again.
Although, installing plasma5-session should at least bring back the desktop.
