studyCommitment - Text that the participant provided in the engagement study. This is stored in the engagement survey activity's client data, which is a flat map where keys are the survey question IDs and values are the answers. (NOTE: For now, we use "studyCommitmentbenefits". Confirm w/ Larsson the correct names once the survey is set up.) Since the survey guid is generated randomly for each env and each study, we get it from engagementSurveyGuid in config.
