const CHAT_CONTENT_CLASS = ‘chat-content’;
const AGENT_USER_TYPE = ‘agent’;
const CHASITOR_USER_TYPE = ‘chasitor’;
const SUPPORTED_USER_TYPES = [ AGENT_USER_TYPE, CHASITOR_USER_TYPE ];
export default class EmbeddedServiceChatMessage extends BaseChatMessage {
messageStyle;
messageText;
isSupportedUserType( userType ) {
return SUPPORTED_USER_TYPES.some( ( supportedUserType ) => supportedUserType === userType );
}
connectedCallback() {
console.log( ‘messageContent value is ‘ + this.messageContent.value );
console.log( ‘User Type is ‘ + this.userType );
if ( this.isSupportedUserType( this.userType ) ) {
this.messageStyle = `${CHAT_CONTENT_CLASS} ${this.userType}`;
if ( this.messageContent.value == ‘test’ ) {
this.messageText = ‘Entered test for testing’;
} else {
this.messageText = this.messageContent.value;
