Retrieve logger fields from Zerolog event

[jackhua222]

I'm planning to use a hook to send logs to elsewhere on top of the logger.
I know that the hook interface is like this:

type Hook interface {
	// Run runs the hook with the event.
	Run(e *Event, level Level, message string)
}

I'm interested to retrieve all the fields I've added to the logger context before sending the logs to elsewhere. I couldn't find anything obvious, is there a way to do this?
