Twilio error "no credentials provided"

Integrations
What have you tried so far?

Tried numerous ways to format the header with the SID and Token, but none have worked i.e. Authorization:, Authorization: Basic, Authorization: Bearer, but none will execute. Returns error 2003 and fails to execute.

In the image, the SID and Token are shown as xxxx and yyyy.

Did you check FlutterFlow's Documentation for this topic?
