Ability to chat nothing using spacebar in new TextChatService?

LegacyChatService allowed you to to press spacebar and chat: ’ ’ (nothing / blank messages)
Where only your name would appear without any message.

In TextChatService it doesn’t register when you add a space and nothing else.
How do you allow sending these empty messages again?

Maybe something like…

player.IsTyping  (input)

if input == "Space" then  

after which it will appear as a blank message. Anyone knows?
