This hint can be set to recommend this notification not be bridged (optional). See Wear OS guides: https://developer.android.com/training/wearables/notifications/bridger#existing-method-of-preventing-bridging
priority – Sets the relative priority for this notification. Low-priority notifications may be hidden from the user in certain situations. Note this priority differs from AndroidMessagePriority
. This priority is processed by the client after the message has been delivered. Whereas AndroidMessagePriority
is an FCM concept that controls when the message is delivered (optional). Must be one of default
, min
, low
, high
, max
or normal

default_light_settings – If set to True
, use the Android framework’s default LED light settings for the notification. Default values are specified in config.xml
https://android.googlesource.com/platform/frameworks/base/+/master/core/res/res/values/config.xml. If default_light_settings
is set to True
and light_settings
is also set, the user-specified light_settings
is used instead of the default value.
visibility – Sets the visibility of the notification. Must be either private
, public
, or secret
. If unspecified, it remains undefined in the Admin SDK, and defers to the FCM backend’s default mapping.
notification_count – Sets the number of items this notification represents. May be displayed as a badge count for Launchers that support badging. See NotificationBadge
https://developer.android.com/training/notify-user/badges. For example, this might be useful if you’re using just one notification to represent multiple new messages but you want the count here to represent the number of total new messages. If zero or unspecified, systems that support badging use the default, which is to increment a number displayed on the long-press menu each time a new notification arrives.
proxy – Sets if the notification may be proxied. Must be one of allow
, deny
, or if_priority_lowered
. If unspecified, it remains undefined in the Admin SDK, and defers to the FCM backend’s default mapping.
