How to update Chronicle SIEM alerts with API?

[JonathanY]

Hi Gurus,

I am new to Chronicle SIEM, I can get alerts with ListDetections APIs(

https://cloud.google.com/chronicle/docs/reference/detection-engine-api#listdetections). 

My client hopes to update alerts with API as what we can do on UI, but I cannot find related update detection APIs in API document. May I know if there is API available to update Alerts?

Thanks
