Tiny workspace or false resolution on Whonix and Virtual Box 7.0.4

I just installed Whonix-XFCE- on Virtual box 7.0.4

Running Windows 10 as a host with:
i9 processor
32gb ram

The resolution is as default 2560X1440

But the full workspace is very tiny, icons are small. It’s not possible to work.

Who can assist?
