Is there a way to resize interface of KDE application in Gnome?

Hello people,
I’m using F38 with Gnome.
I needed Kleopatra, so I installed it via DNS.
The interface is too small on my screen compared to other apps.
I’m unable to change the dimension. Playing with the font in each application never satisfies me.
Is there a setting somewhere so I can tweak KDE apps to have a larger “size”?
