lex bot how to get a identitypoolid? /

I want to escape my LexBot in a browser. HTML Web page is ready and runs on S3. Lex bot is also ready and published. Just need the IdentityPoolid. See below:// Initialize the Amazon Cognito credentials provider AWS.config.region = 'us-east-1'; // Region AWS.config.credentials = unique AWS.
CognitoIdentityCredentials({ // Provide your Pool Id here IdentityPoolId: 'us-east-1:XXXXX', });
