Detailed description of a problem

according to index.d.ts, playerChat event's data looks like this:

interface ServerPlayerMessage {
  formattedMessage: string
  message: string
  type: string
  sender: string
  senderName: string
  senderTeam: string
  verified?: boolean | undefined
}

but this is inconsistent according to API.md:

Called when a chat message from another player arrives. The emitted object contains:
* formattedMessage -- (JSON) the chat message preformatted, if done on server side
* plainMessage -- (Plaintext) the chat message without formatting (for example no `<username> message` ; instead `message`), on version 1.19+
* unsignedContent -- (JSON) unsigned formatted chat contents ; should only be present when the message is modified and server has chat previews disabled - only on version 1.19 - 1.19.2
* type -- the message type - on 1.19, which format string to use to render message ; below, the place where the message is displayed (for example chat or action bar)
* sender -- the UUID of the player sending the message
* senderTeam -- scoreboard team of the player (pre 1.19)
* senderName -- Name of the sender
* targetName -- Name of the target (for outgoing commands like /tell). Only in 1.19.2+
* verified -- true if message is signed, false if not signed, undefined on versions prior to 1.19

from testing (on 1.19.4), I found that it looks something more like this:

interface ServerPlayerMessage {
  formattedMessage?: string
  plainMessage?: string
  unsignedContent: string
  type: number
  sender: UUID
  // no senderTeam (since only pre-1.19)
  senderName: string
  targetName: string | undefined
  verified: boolean
}

Expected behavior

index.d.ts = API.md = "real life" (testing)
