MacBook Pro M2 desktop is no longer accessible with 2 external monitors

(2) DELL U34145W monitors, attached to MacBook Pro 14" M2, MACOS 13.4.1 - MacBook screen, and two external monitors are powered on and I can see the desktop for each. I can move Windows from one Dell Monitor to another but not to the MacBook pro screen. I cannot access the MacBook Pro screen with my mouse, either. (I have the two Dell Monitors on either side of the MacBook. When I move a window from one monitor to the other - it goes straight from one monitor to the next - without any sign of the mouse or window or anything passing through the MacBook Screen - again - cannot access the windows on the MacBook screen with my mouse in this configuration - did not see anything to be changed in the SETTINGS → Display on the MacBook - no option to add a second external monitor. Thanks
