Having used OneSignal in the past, there is a whole metric ton of options when sending push notifications I have noticed. For example, the ability to change the accent color. I am assuming that we could specify for Android to do this, in the AdvancedPlatformDelivery list, but I am unsure how this would work.
for the AdvancedPlatformDelivery parameter, would I pass something like:
{"Platform":"GoogleCloudMessaging","Json":{"AccentColor":"#FF9900FF"}}
How would I find documentation on what options here would be available, and how to format them?
