I wrote that script and in header section there is special comment for action recording so I made sure that Action panel would be able to catch it.
I see difference between how Action panel interprets the action
{"_obj":"javaScriptOptionsClass","_target":[{"_enum":"ordinal","_ref":"document","_value":"targetEnum"}]}
vs Occultist
{
_obj: 'a0754df2-9c60-4b64-a940-6a2bb1102652',
_target: [
{
_ref: 'document',
_enum: 'ordinal',
_value: 'targetEnum'
}
]
}
Descriptor from Occultist should work.
