It&#x27;s not out of date. Chrome does not yet support Message Payloads in the public release, here&#x27;s their description for it on chromestatus.com: <a href="https:&#x2F;&#x2F;www.chromestatus.com&#x2F;feature&#x2F;5746279325892608" rel="nofollow">https:&#x2F;&#x2F;www.chromestatus.com&#x2F;feature&#x2F;5746279325892608</a><p>The workaround for now is to have the service worker fetch the payload from an API endpoint that the sender implements themselves.
