Not working in Windows 11 when laptop lid is closed

Not working in Windows 11 when laptop lid is closed

Hello,
I am trying to use Assist Unattended to access a laptop, using Windows 11,  whose lid is closed.  The power settings are set to "Do Nothing" when it's closed, but I can't control anything.  The mouse doesn't work, the keyboard doesn't work, and sending control sequences from Assist (ctrl-alt-del) doesn't work.
Is there a setting I need to change?
Thank you/
