Cognito Identity Pools (CIP): Cognito Events: Sync Trigger

Good day everyone,

I got as far as setting up the CIP syncTrigger in the resources section under CognitoEvents key. This follows the SyncTrigger schema identified here:

However, I’m stuck at how to link the function that consumes this trigger. For a User Pool trigger I can use the events: -cognitoUserPool: attribute. Is it the case that Serverless only supports Cognito User Pool triggers and no other Cognito triggers? It’s a shame because there are Cognito Events and Cognito Streams under the CIP service that are very useful
