Cannot find 'DynamoDB event stream role'

[jyothri]

I was following the guide and at this step

In the 'Lambda function handler and role' section, select the 'DynamoDB event stream role' option. This will open a new window to create an Identity and Access Management Role (IAM). Click the blue 'Allow' button to enable the creation of the role. This is necessary to enable permission for DynamoDB to invoke your Lambda function

However I don't see the option of DynamoDB event stream role. I have attached the screenshot of the options I see. I am guessing I have to do custom role? Also attached is the screenshot when I choose custom role. Please guide me on how to proceed?
