How to remove a RTPC from a sound object using WAAPI

Question

what I want specificly is to batch delete RTPCs

ak.wwise.core.object.delete seems to only work on sound objects and buses(I get an error message saying "can't delete object" when trying to delete RTPCs)

I have tried 2 other methods:

1.Using "ak.wwise.core.object.set" to set @RTPC to an empty array, this doesn't work because it seems to only append to the RTPC array, not overwrite it

2.Using "ak.wwise.core.object.setProperty" to set the RTPC property to an empty array, but this keeps raising an error "property doesn't exist on the object"
