I realized there is probably an even easier way (no custom ELisp
required), simply by creating a separate child heading for the meeting,
which should then show up.  Assuming I am following you correctly, how
about:

#+begin_src org

* PROJECT Project X
  :PROPERTIES:
  :CATEGORY:             P:X
  :END:

** PROJECT Discuss 'topic' with Steve

*** DONE Ask Steve for a time-slot

*** Meeting with steve
<2022-04-05 Tue 14:00>--<2022-04-05 Tue 15:00>

#+end_src

N.B. the indentation levels.

Couple notes here:

1. If you set CATEGORY on the parent, and have enabled inheritance, the
'P:X' should appear on left side in your agenda, at the time of this
meeting, giving context.  The 'P:' convention is just what I use to
denote a Project (as opposed to an Area).

2. I follow GTD here, where anything with more subtasks is itself also
considered another 'project'.  You don't have to.  In fact one of my
todo keywords is actually PROJECT.

3. I guess you could use SCHEDULED just as well, but if you carefully
read the manual, this is not the intent of SCHEDULED.  An appointment
(like this) should simply be a time slot (as I showed above).  You can
of course do whatever you like.  :)

I have included some things here that I might do which are not strictly
necessary to solving your problem, but hopefully you can adapt this to
your needs.
