Zoom 6.7 - Linux: icons & fonts in UI navigation far too small (no proper scaling on hi DPI monitor)

Is there any workaround / solution for this problem:
I just upgraded to the latest Zoom version 6.7 on Linux and the icons and fonts in the new navigation menu are far too small (for me).

The Accessibility settings have several scaling options but this excludes the navigation itself.

I am on a high DPI monitor and all other programs scale properly but Zoom seems to ignore the scaling configuration.

My system: Ubuntustudio 24.04
