Can I use my MacBook as a third monitor for my Windows 11 computer (Host)?

Is it possible for the client computer to act as a third monitor when I bring it into the office and remote into my Dell?

When I turn on Virtual Displays, the host computer goes black. I do not have Privacy mode on. Toggling it on/off does nothing, the host computer stays black and monitors go on standby. When I turn off Virtual Displays (and I keep retina off because it gets way to big on client computer), privacy mode acts as it should turning it on/off but the client is simply mirroring per usual. Any way to make the client a third monitor?

Dell - Windows 11 Pro - Jump Connect version 7.1.45. In advanced settings, Fluid Remote Desktop is on.

MacBook Air M1 (Mac OS Sequoia 15.1, running Jump Desktop version 9.0.93)
