Authorize user apps with and without PKCE

Use this endpoint to authenticate user apps using fabric Identity. When calling this endpoint, the immediate response will be a browser redirect to the hosted Login page configured in fabric Identity. After successful authentication of the user on the hosted Login page, fabric Identity will redirect back to the user app using the provided redirect_uri. This endpoint supports both authorization code flow with and without Proof of Code Exchange (PKCE).
Note: This endpoint isn’t required for system app authentication (refer to /token endpoint instead)
