Create a test participant for a researcher

### Overview Creates a test participant with the same details as the researcher and the supplied email. This participant will bypass any fraud checks and on-boarding steps. ### Enabling the feature This endpoint is only enabled for select workspaces and will need enabling before the endpoint can be used. ### Participant Limitations - The participant will be limited to take studies only in the workspaces associated to the researcher and where the feature is enabled. - The participant will not be able to cashout any balance earned from completing studies. ### Usage - The API response contains the participant ID. This can be used in a custom allowlist or participant group to target the participant on studies. This enables the researcher to test the study set up end-to-end. - A randomly generated password is assigned to the participant account. We recommend that you request to reset the password, and use this new password to login to the participant account.
