processChatMessageInternal

private boolean processChatMessageInternal(MessageType.Parameters params,
 SignedMessage message,
 Text decorated,
 com.mojang.authlib.GameProfile sender,
 boolean onlyShowSecureChat,
 Instant receptionTimestamp)

Processes a chat message.

If the message cannot be verified due to a broken chain, this disconnects the client from the server.

The message can still end up not being displayed if the verification fails and onlyShowSecureChat is true or if the sender is blocked via the social interactions screen.

This adds the message to the hud, narrates it, and appends it to the chat log.

Parameters:

receptionTimestamp - the timestamp when the message was received by this client

Returns:

whether the message was actually displayed
