[estebanabaroa]

it's already added to the readme

Challenge {
  type: 'image/png' | 'text/plain' | 'chain/<chainTicker>' // tells the client how to display the challenge, start with implementing image and text only first
  challenge: string // base64 or utf8 required to complete the challenge, could be html, png, etc.
  caseInsensitive?: boolean // challenge answer capitalization is ignored, informational only option added by the challenge file
}

should be added to the return of captcha-canvas-v3 challenge

  return {challenge, verify, type, caseInsensitive: true}

and passed to the ChallengeMessage.challenges
