Claims or Name in IDP response

Hi,

The requirement is to integrate OIF with Amazon cognito. Where OIF is IDP and Cognito is SP.

The requirement is SP initiated SSO flow.

Amazon incognito expects a name or claim in IDP response.

1) May i know how to set name or claim with the below configuration?

2) Do we need to make any configuration changes to send the name or claim in the IDP response?

3) We provided the default metadata file without making any changes, for achieving the below do we need to send a custom metadata file to the SP?

4) We are not sending any additional attributes in the SP-attribute profile.
