PolicyKit asks for root password for Timeshift when using Pcloud drive

I have a Pcloud drive appimage in my Plasma install. I haven’t used pcloud drive for some time now in my laptop, because I usually do it in my phone. Now I noticed weird behavior when I try to click “open drive” in pcloud taskbar icon. It opens a box where it asks root password for Timeshift. Is this some kind of problem with KDE Polkit agent and how do I fix it?
