Full Code

PlayerEvents.decorateChat(event=>{
    const msg = event.getMessage();
    event.setMessage(Text.of(msg).clickSuggestCommand(msg).hover(Text.of("+1")))
})

After a player sends a message, the script rewrites the message component so it can be clicked to suggest the same text in chat input, and hovering shows a +1 tooltip.
