Thermal monitor widget plasma 5

Every time I install a new version of leap I put a couple of these on the Plasma desktop for my cpu and gpu temps. I like to put the Trinity desktop in after that but it seems every time I do that the monitors no longer appear on the Plasma desktop and I can’t add them as new widgets.

Any help getting them back?

Trinty is KDE3, the Widgets are written for Plasma5…

I know that. After I install Trinity the widgets in stop working in Plasma. I am not trying to use the widgets in Trinity.

Ah, that was not clear to me.
