According to documentation, the structure of NotificationOptions supposed to be as the following:

appIconMaskUrl
string optional
Deprecated 59+
The app icon mask is not visible for Mac OS X users.

A URL to the app icon mask. URLs have the same restrictions as iconUrl.

The app icon mask should be in alpha channel, as only the alpha channel of the image will be considered.

buttons
NotificationButton[] optional
Text and icons for up to two notification action buttons.

contextMessage
string optional
Alternate notification content with a lower-weight font.

eventTime
number optional
A timestamp associated with the notification, in milliseconds past the epoch (e.g. Date.now() + n).

iconUrl
string optional
A URL to the sender's avatar, app icon, or a thumbnail for image notifications.

URLs can be a data URL, a blob URL, or a URL relative to a resource within this extension's .crx file Required for notifications.create method.

imageUrl
string optional
Deprecated 59+
The image is not visible for Mac OS X users.

A URL to the image thumbnail for image-type notifications. URLs have the same restrictions as iconUrl.

isClickable
boolean optional
Deprecated 67+
This UI hint is ignored as of Chrome 67

items
NotificationItem[] optional
Items for multi-item notifications. Users on Mac OS X only see the first item.

message
string optional
Main notification content. Required for notifications.create method.

priority
number optional
Priority ranges from -2 to 2. -2 is lowest priority. 2 is highest. Zero is default. On platforms that don't support a notification center (Windows, Linux & Mac), -2 and -1 result in an error as notifications with those priorities will not be shown at all.

progress
number optional
Current progress ranges from 0 to 100.

requireInteraction
boolean optional
Indicates that the notification should remain visible on screen until the user activates or dismisses the notification. This defaults to false.

silent
boolean optional
Chrome 70+
Indicates that no sounds or vibrations should be made when the notification is being shown. This defaults to false.

title
string optional
Title of the notification (e.g. sender name for email). Required for notifications.create method.

type
TemplateType optional
Which type of notification to display. Required for notifications.create method.

However, in latest (0.0.145) version DT structure of NotificationOptions is different:

interface NotificationOptions {
    actions?: NotificationAction[];
    badge?: string;
    body?: string;
    data?: any;
    dir?: NotificationDirection;
    icon?: string;
    image?: string;
    lang?: string;
    renotify?: boolean;
    requireInteraction?: boolean;
    silent?: boolean;
    tag?: string;
    timestamp?: number;
    vibrate?: VibratePattern;
}

For example, missing "title" property. Instead of "iconUrl" there is an "icon". And so on.

Do I missing anything?
