После публикации бота, пользователю необходимо сначала пообщаться с ним, чтобы отправить проактивное сообщение. Я следовал этому примеру , но вместо того, чтобы хранить ссылку на разговор в переменной, я сохранил ее в cosmosDB. Однако я все еще не могу отправить проактивное сообщение, если пользователь не общался с ботом после публикации. Есть ли способ отправить проактивное сообщение, даже если пользователь не общался с ботом после публикации?
