how to turn on the bool threshold_negative_intensity from the python wrapper?

Hi, I am trying to simulate a Hawkes Process using the python wrapper and since it contains some negative intensity kernels, the total intensity is sometimes going negative leading to this error:
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call last)

2 if True:
3 hawkes.track_intensity(dt)
----> 4 hawkes.simulate()
5 timestamps = hawkes.timestamps

128 def reset(self) -> "void":
RuntimeError: Simulation stopped because intensity went negative (you could call ``threshold_negative_intensity`` to allow it)
How can I set this boolean to True from the python wrapper? Any help is highly appreciated.

Found the method threshold_negative_intensity()
