aGate on Nostr: I'm looking for real-life examples of Announce activities sent by ActivityPub servers ...

I'm looking for real-life examples of Announce activities sent by ActivityPub servers such as Mastodon, Pleroma, Firefish, etc.

This activity is sent when a user boosts a post.

I can't seem to find any, it probably looks like :

{
'@context': 'https://www.w3.org/ns/activitystreams';,
id: 'foo',
type: 'Announce',
actor: 'https://example.com/actor';,
object: {'id' : 'http://post';}
to: 'http://example.com/followers';
}


But I'd like to see exactly what fields are included, in particular in the object property.

Boosts welcome.
