How to pass in parameters for Step Functions EC2 Service API DescribeTags?

Question

I am learning Step Functions and I want to get a list of EC2 instances that matches my filter. I am not able to use the parameters described here: 
https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeTags.html

I have tried using using `Filter` as an array and as numbered like `Filter.1` (see screenshots)

I am able to run the step function with empty parameters.

Looking at the Boto3 documentation [1] for this method, it looks like you need to provide the `Filters` parameter like this:

```
"Filters": [
  {
    "Name": "tag:Group",
    "Values": [
      "Production"
    ]
  }
]
```
