closing cover on macbook air with big sur turns off external display

I have followed the suggestions for changing settings in the power saver but closing the lid still turns off the external display. Any other suggestions?

MacBook Air 13″, macOS 11.6

If you want the lid closed and external monitor still on -- aka "clamshell mode"

connect MBA to power source
have external keyboard and mouse connected (wired or wireless)
connect to external monitor
boot up the system, then close the lid
