Close Cubase when song closes

Hello!
I want to make it so that when I close my song, Cubase should close as well.
I didn’t find a way to set this setting.
Currently I have to click the “X” twice:
First I close the song, then the Cubase menu is still open, and I need to close this separately as well.

This is very annoying.
How do I set a setting that would automatically close the Cubase menu bar as well when I close the song?

Thank you!
