widget
Looks and sotres at window.localStorage.userData for customer info. So, if you have a logged application and wants the chat widget to use your logged customer information, just put the following object at localStorage before adding <ChimpWidget>:
let userData = { "name": LOGGED_USER_NAME_FROM_YOUR_SITE, "id": LOGGED_USER_ID_FROM_YOUR_SITE, "avatarURL": LOGGED_USER_AVATAR_FROM_YOUR_SITE}window.localStorage.userData = JSON.stringify(userData)
