expandChatOverlay()

This function does the opposite of collapseChatOverlay. You can supply some optional parameters to either have a prefilled message or automatically send a prefilled message. You can experiment with this by going to the dev sandbox and pressing the buttons 'Expand SDK', 'Prefilled message "I need help with my phone"', and 'delayed auto-sent message "Help me with my phone"' to trigger the different functionality. Here is the function API and some example usage:

export type ExpandPayload = {
    message?: string;
    autoSend?: boolean
};

/**
 * Will open the chat bubble to display a ChatOverlay that allows the customer to send messages
 * @param payload - includes an optional message that will prefill the input box
 */
export const expandChatOverlay = async (payload: ExpandPayload): Promise<void>;

// Example usage:
const someFunction = () => {
    // Just open the chat bubble
    expandChatOverlay();
    // Open the chat bubble with a message prefilled
    expandChatOverlay({ message: 'Hi I need help with my phone!' });
    // Open the chat bubble with a message auto sending
    expandChatOverlay({ message: 'Hi I need help with my phone!', autoSend: true });
}
