Problem with cross-region events

Hi, when I created the central event bus in account B in us-east-1 and the event bus in account C in us-west-2.

I received the following error:

CREATE_FAILED     AWS::Events::Rule    InvoiceProcessingRule  

Cross-region API call is not allowed. (Service: AmazonCloudWatchEvents; Status  Code: 400; Error Code: ValidationException; Request    ID: XXXXXXXX; Proxy: null)    

to deploy I ran the commands from the readme

sam deploy --guided --region us-west-2

Sam version: SAM CLI, version 1.90.0

In the same region, all is good but I have these restrictions and I need to use different regions. Am I missing something?

Incorrect description of EventBusName

Incorrect description of EventBusName in this template
It's not the name of the central event bus, but invoice processing event bus.
