Description

• In IS-7.0.0, IS-7.1.0, and IS-7.2.0 supports custom HTTP based SMS provider configuration.
• The UI configurations don't have a specific field to configuring authorization details
• What supported is, configure relevant Authorization header under Headers section along with other headers
  eg:
  If using basic auth -> Authorization: Basic <base 64 encoded username:password>
  If using bearer token -> Authorization: Bearer <obtained token>

Having the explaination clearly on how to configure Authorization header in both of these common cases would be easier to understand for the user
