How can I create cryptomatte AOV with python script?

[an_jp]

Actually,I can make AOV by python command,but the shader does not made and
nothing is rendered.
So I want to know how to make the cryptomatte shader with python script.

make AOV with command here:

aovs.AOVInterface().addAOV('crypto_asset' )
aovs.AOVInterface().addAOV('crypto_material' )
aovs.AOVInterface().addAOV('crypto_object' )

import mtoa.aovs
mtoa.aovs.AOVInterface().addAOV('crypto_asset', aovShader='cryptomatte' )
