Setting the X Windows forwarding for your own personal user is usually set in the .profile file, but most of the time you really want to enable X Window forwarding for all users of the system.  I mean you already went through the trouble of setting up the X Windows receiver so why not enable for all users?

I recommend installing X410 as it is the best I have used on Windows 10, but the free older option is X11 Xming for Windows which works ok in my opinion will definitely need to be tuned for fonts, etc. Further details for X11 Xming https://siliconheaven.info/xlaunch-configuration-file/

Add a file to the following path to make sure it gets loaded for all users of the system

/etc/profile.d/<something_identifying>.sh

Put this line in the file

# enable external x display
export DISPLAY=:0
