Some events will get published to kinesis stream in A account once the event got published kinesis must trigger the lambda from B account. Also please confirm whether I can achieve my use case or not?

Hi folks, I have added the resource-based policies to AWS kinesis stream. Once after adding that policy How it will work? I have assumed some working scenario for the below following cases for the above policies: Case 1: Can a kinesis stream from A account with invoke the lambda function from B account automatically when event is published to kinesis streams? Case 2: Or we can have Event bridge on top B account lambda which will read the data from A account kinesis on certain intervals?

My goal is to achieve this use cases : Some events will get published to kinesis stream in A account, once the event got published kinesis must trigger the lambda from B account. Also please confirm whether I can achieve my use case or not?
