Direct_messages/indicate_typing not working


#1

Hello!
I try to send a typing indicator via REST for user.
I read this doc https://developer.twitter.com/en/docs/direct-messages/typing-indicator-and-read-receipts/api-reference/new-typing-indicator
send a request to https://api.twitter.com/1.1/direct_messages/indicate_typing (not a https://api.twitter.com/1.1/direct_messages/indicate_typing.json - got 404 error) - recieve a 204 response status code, its all OK.
But typing indicator is not appear in mobile app or browser.
Whats wrong?
