      intent: Exchange a code or refresh an access token
      effect: write
      questions:
      - What do I send to Flexpa to swap a Link authorization code and PKCE verifier for a Patient Access Token?
      - Can I renew an expired patient token with a refresh token instead of sending the patient through Link again?
      - Which grant mints a server-to-server Application Access Token from my publishable and secret keys, and how long does it last?
      instructions:
      - text: Exchange authorization code {code} with PKCE verifier {code_verifier} for a Patient Access Token.
        slots:
          code: requestBody.code
          code_verifier: requestBody.code_verifier
      - text: Renew the patient's access using refresh token {refresh_token}.
        slots:
          refresh_token: requestBody.refresh_token
      - text: Mint a 30-minute Application Access Token with the {grant_type} grant.
        slots:
          grant_type: requestBody.grant_type
