If you are logging in to Raydiant Engage with your Salesforce credentials, it means that your admin has added you through the Salesforce connector.
In this case, Raydiant Engage is reflecting your name and email as they appear in your Salesforce user profile, and they cannot be edited in the Raydiant Engage interface. If you need to make a change, please contact your Salesforce admin so they can update your profile within Salesforce.
