Customize Partner Event Source name in AWS CloudFormation script

Question

I want to define the AppFlow configuration in a SAM template.

I don't want to let AWS automatically generate a Partner Event Source name like aws.partner/appflow/salesforce.com/${AWS::AccountId}/resource

It is possible to specify a custom name when setting up AppFlow manually via console (see step 4 in Amazon EventBridge.

I cannot find the right keyword to specify the name in CloudFormation (I guess it should go somewhere under AWS::AppFlow::Flow but the solution eludes me.)

TIA

The solution is to set AppFlow::Flow:DestinationFlowConfigList::DestinationConnectorProperties:EventBridge:Object to the suffix you want the source to have!

E.g.:

  SalesforceAppFlow:
    [...]
    Type: AWS::AppFlow::Flow
    Properties:
      [...]
      DestinationFlowConfigList:
        - ConnectorType: "EventBridge"
          DestinationConnectorProperties:
            EventBridge:
              Object: THIS_SUFFIX
    [...]

  PartnerEventBus:
    Type: AWS::Events::EventBus
    Properties:
      Name: !Sub "aws.partner/appflow/salesforce.com/${AWS::AccountId}/THIS_SUFFIX"
      EventSourceName: !Sub "aws.partner/appflow/salesforce.com/${AWS::AccountId}/THIS_SUFFIX"
    DependsOn: SalesforceAppFlow
   [...]
