Extra monitor and macbook air m1 lid closing?

Question

macOS

Hello! There is a MacBook Air (monterey), a monitor is connected to it in the additional monitor mode. The problem is that when you close the lid of the MacBook, all windows go to the additional monitor and the monitor itself does not turn off, but you need it to turn off. Is this possible? Thank you!

Answer 1

As far as I remember: the only option is to force sleep mode and close the lid
UPD:
Googling led to such a script https://github.com/pirj/noclamshell
Out of the box with an external monitor connected, it is impossible to send to sleep by closing the lid
