If you're looking for direction, you'll need two of them
I'd be tempted to use a resistor and neon with a one KV diode in series with the neon.? The neon will limit the maximum voltage to about 100 volts or so.
so:? resistor connected to a neon with a series diode, connecting both across each other, and the diodes reversed.
Might be a good idea.

Could you use a small (NE-2) neon bulb for this? I recall holding the lead
of one and shuffling across a carpet. I got the bulb to flash.

The LEDs would protect each other from reverse breakdown. They should be
stout enough to take the forward hit and flash. If not, you can put some C
across them or R in series to soften things up (which would also stretch
the pulse for better visibility). Try it and see.
What's really needed to assess part durability is a power rating and an
energy rating. You won't find energy rating for LEDs, so have to
experiment. If you study the HBM you'll have an idea of the energy
available from your own spark. Unfortunately, I don't think there's a spec
for SCM, but you can be sure it would be quite a bit more C, and nearly
zero R. Good luck.
