Instantiate a new Pubnub instance. Only the subscribeKey is mandatory. Also include publishKey if you intend to publish from this instance, and the secretKey if you wish to perform PAM administrative operations from this JavaScript V4 instance.
It is not a best practice to include the secretKey in client-side code for security reasons.
When you init with secretKey, you get root permissions for the Access Manager. With this feature you don't have to grant access to your servers to access channel data. The servers get all access on all channels.
Set restore as true to allow catch up on the front-end applications.
