EventBridge Scheduler targeting SQS FIFO queues is useless for rates less than 5 minutes

Question

Can someone please confirm that I am understanding this correctly?

1. GOAL: Use Event Bridge Scheduler to target an SQS FIFO queue at a rate of every 1 minute.
2. Based on this (https://docs.aws.amazon.com/scheduler/latest/APIReference/API_SqsParameters.html), the first paragraph states: "If you specify an Amazon SQS FIFO queue as a target, the queue must have content-based deduplication enabled."
3. Based on this (https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues-exactly-once-processing.html), the deduplication interval is hard-coded to 5 minutes.

My understanding then is that 4 out of 5 of the attempts to queue the message will fail silently as "accepted but duplicate".

The evens that EventBridge Scheduler pushes to the queue are different every minute, so there will not be deduplication.

See the following two events. You can see that there is a different `id` as well as a different `time` field:

```
{"version":"0","id":"1164d9e9-31a8-419f-b38e-5a1d803fce6e","detail-type":"Scheduled Event","source":"aws.scheduler","account":"XXXX","time":"2023-08-14T08:43:29Z","region":"eu-west-1","resources":["arn:aws:scheduler:eu-west-1:XXXX:schedule/default/Fifo"],"detail":"{}"}

{"version":"0","id":"1164d9e9-6da8-419f-b38e-5a1d803fce6e","detail-type":"Scheduled Event","source":"aws.scheduler","account":"XXXX","time":"2023-08-14T08:44:29Z","region":"eu-west-1","resources":["arn:aws:scheduler:eu-west-1:XXXX:schedule/default/Fifo"],"detail":"{}"}
```
