How can I ssh -X from a non-macOS machine into a macOS machine and run X11 programs displaying on the non-macOS host?

I have a macOS machine running Catalina. I have also have a Linux machine, running Ubuntu 20.04. I want to ssh from the Linux machine to the Mac by a command such as ssh -X user@macos-machine. When I try to do this, I get the error message "X11 forwarding request failed on channel 0". The ssh itself works, as I get a shell running on the Mac and displaying on the Linux, but programs like xeyes and xterm give errors like "Can't open display:" (For reference, the DISPLAY variable does not get set.) The xeyes and xterm executables exist on the macos machine, and they work if i use XQuartz.app. That is, if I am at the console of the macOS machine, xeyes and xterm work and display on the macOS machine. My Linux machine can successfully run ssh -X to other Linux hosts, so I think I have to do something to the macOS host. None of the machines has X11Forward turned on (or off) explicitly in /etc/ssh/ssh_config and I would like to avoid directly editing files in /etc if some other, more macOS -like, solution exists.
