according to the Ukrainian Air Force, English Royal Air Force and French Air Force only the SU-24Ms have been modified to carry and launch Storm Shadow and Scalp cruise missiles.
They can launch but the launch isn't fully supported. They aren't dumb firing, so some integration is needed - you can't just strap the missiles to a Gulfstream then light the engines - but the missiles aren't using the host plane's systems for initial guidance (or use it in a degraded mode). Not all the bells and whistles are turned on because the on-board avionics aren't up to snuff and can't pass all the data to the missile that it is expecting, or at least not in manner, timeliness, or format it can use.
For HARMs specificially, this means they launch in (effectively) only terminal guidance mode without the aid of GPS target fix to keep things on track if the RADAR it was locked to shuts off. This is a big determent now that Russians aren't just leaving their RADAR on 24/7, and why its been down to drones to make the kills.
In the case of Storm Shadows, this means the targets need to be pre-programmed on the ground and launches need to happen from a pre-planned area/altitude/airspeed so the missile has a general starting point for its initial position fix since it can't get that from the aircraft.
The lack of GPS targeting data to pass to weapons probably matters less for these cruise missiles because they are advanced enough to recalculate their positions in flight and Russian GPS-jamming at most high-value targets (ie Crimea Bridge), so they are probably operating on inertial guidance anyway for terminal approach. Or as in the Kilo/Ropucha strike getting targeting data from the ground.
tl;dr there is a reason they aren't getting Air-launched radar guided missiles (HARM asside, but that's using the target's radar to lock on)
