__________________ APIs are used to create a new ACD web chat and interface on behalf of the guest (customer) participant.

The term "guest chat" specifically refers to the APIs that facilitate the creation of a new Automatic Call Distribution (ACD) web chat session on behalf of the guest or customer participant. This nomenclature highlights the role of the end-user or customer in the interaction, emphasizing that the APIs are designed to initiate a chat experience from the customer's perspective.

Such APIs allow for seamless communication and interaction between the service provider and the customer, ensuring that the chat interface is appropriately set up to handle inquiries, support requests, or other forms of customer service. This is essential for delivering a robust customer experience as it allows for instant engagement without requiring the customer to authenticate or register before reaching out for help, which is typical in a guest scenario.

In contrast, other options do not directly represent the specific functionality tied to initiating a chat on behalf of a customer participant. They may refer to different aspects of chat interfaces but do not capture the essence of facilitating a new ACD web chat session specifically for guests.
