Hey Medplum Team, I'm setting up a rest-hook Subscription on Encounter creations to contact an endpoint for sending push notifications. For handling authentication on this endpoint we would like to pass some auth headers from the Subscription, but I am seeing that the

header

field of

channel

accepts an array of strings. What is the proper format for this array of strings for passing an authorization header? Something like

["Authorization=bearer <TOKEN>"]

?
