Access to all response headers in Custom Connector

Hi

I'm connecting to an API that provides a pagination token (scroll-id) in the response header.

I need that ID to include in the next query to receive the next items.

The response header comes with various items.

However, when trying to read the header items it seems that the header only includes the "Content-Type" item

let    
    Source = Web.Contents(url, header),
    scrollid = Value.Metadata(Source)[Headers]
in
   scrollid

While in Fiddler I do see all other items as well.

I know it requires a custom connector to access all headers from other posts here, but I haven't found a solution how to actually acess all those header items.

Thanks for your help,

Chris
