Field or Parameter in NR Alerts API for NRQL Condition to set time limit

UI addition of NRQL condition allows setting incidence auto-close window, but API does not?

I’m looking to create NRQL conditions via the v2 alerts api as detailed in the api docs.

I seem to be unable to set an incidence time limit.

Specifically I’m looking to be able to set this value I see in the UI, but don’t seem to be able to set in the API:
violation_time_limit

Anyone have any ideas?
