The easiest way to do this is to become the "other user" by running:

ssh -X otheruser at localhost

You can check that X forwarding is allowed by running:

echo $DISPLAY

As the otheruser in that terminal.  If DISPLAY is unset, then you'll need
to edit the sshd_config file, set "X11Forwarding yes" and restart sshd.

Then you can run your X application in the terminal, and it will be
forwarded into your current X session.

There are other ways, but that's probably simplest and more secure than
some other possibilities.
