Logic Apps - Http+Swagger - Header attribute for token based authentication

Question

I am trying to add headers to a Http+Swagger action in Logic App.

When I add a simple Http Action, I can clearly see the Headers in the designer. However, with Swagger+Http action it disappears.

I am using token based authentication and need to add Header to this API call. Hence, I modified the code view like below but it does not seem to help!

Cannot find much resources with regards to this. Any help is appreciated.

Thank You.

The official documentation states to make use of the parameters to send and receive a token.

"parameters": {
               "secret": {
                  "type": "SecureString"
               }
            }

Or you can try like this

"HTTP": {
    "inputs": {
        "headers': { 
        "Authorization": "@concat('Basic ', base64('username:password'))",
        "Content-Type ": "application/json"
    },
    "method ": "GET ",
    "uri": "someurl"
   },
   "runAfter": (),
   "type": "Http"
   }
