Subscribing SQS Queue to SNS Topic cross-account

Example stack for subscribing to topics from various accounts from a single consumer account:

from aws_cdk import aws_sns, aws_sqs, aws_lambda, aws_lambda_event_sources, aws_sns_subscriptions
import aws_cdk

TOPICS = {
    'my-event-eu': 'arn:aws:sns:eu-north-1:12345689012:my-event',
    'my-event-us': 'arn:aws:sns:us-east-1:34568901234:my-event',
}

class TopicSubscriptionStack(aws_cdk.Stack):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)

            runtime=aws_lambda.Runtime.PYTHON_3_12,
            code=aws_lambda.Code.from_asset('./lambda'),
        )

        for event_name, topic_arn in TOPICS.items():
            topic = aws_sns.Topic.from_topic_arn(
                scope=self,

            )
            log_lambda.add_event_source(
