HTTP OAuth 2.0 using token

Hi there, I am new to the make community so please excuse the question !! I have an API connection to an app called Lightspeed - I have tested the connection in Postman using a bearer token.

When I enter these credentials into the http OAuth2.0 module and create a connection:

I get the following error
{“errors”:[{“code”:“unauthorized”,“title”:“Full authentication is required to access this resource”}]}

Any help would be appreciated
