Get SQS URL Name from within Serverless function?

Question

I would like to grab the name of the serverless function. Here is my code. What I am trying to achieve is, instead of arn https://sqs.us-east-1.amazonaws.com/xxxx/channels.fifo, I want to the env SQS_URL to be set to channels.fifo. I looked at Fn::Split fucntion of cloudformation, but was unable to properly use it to set it on env.

functions:
  S3ToSqs:
    handler: lambda_function.lambda_handler
    role: S3ToSqsLambdaRole
    memorySize: 128
    timeout: 5
    events:
      - schedule:
          name: 'S3ToSqsCronEvent'
          rate: rate(1 minute)
          enabled: true
    environment:
      SQS_URL:
        Ref: sqsQueue
      REGION: 'us-east-1'

If you take a look at the SQS::Queue CloudFormation resource you can see that the Queue Name is exposed as an attribute.

As a result of that you can use: !GetAtt sqsQueue.QueueName or Fn::GetAtt [sqsQueue, QueueName], both of which may be a little easier to read than the solution you came up with (which still works).
