MiccSDKMiccSdk WebHook api calls

I am attempting to use the MiccSdk WebHook api calls. There are two fields on which that I cannot find any documentation. The Event and the Filters fields. I assume that, like the notifications api in cloudlink, this would be where I setup what event (ex ringing) and things like endpoints. Does anyone have any ideas or where to find more information or where I can find specific examples. The only samples I can find on Git are for the other apis.
