## Type Declaration

### chats?

> `optional` **chats**: [`Chat`](../classes/Chat.md)[]

Optional: every chat created with `defineChat()` is managed anyway. Pass it
to fix the order of the chat list.

### seenStore?

> `optional` **seenStore**: [`SeenStore`](SeenStore.md)

Where the cross-save seen record lives.

#### Remarks

Defaults to the engine's settings table. Pass
`createMemorySeenStore()` to opt out of cross-save tracking, or your own
implementation to persist it elsewhere.
