Sketchup 2023 Mac Toolbar lost small icons option?

Seems like Sketchup 2023 Mac version lost it’s ‘small icons’ option when customising the Toolbar.
In my 2022 pro I could choose “Use small size” icons, but that option has vanished in the latest 2023.1 version.

It will be great to resolve this issue and gain again the scarce space on the laptop toolbar.
