hello , i m a student . I am currently using Google Colab to run Rasa. However, when I interact with the Rasa Shell to input commands or responses, the characters I type appear as filled circles, similar to the way passwords are masked for security. This makes it difficult for me to see what I’m typing and effectively interact with the chatbot. I’m seeking assistance to resolve this problem and ensure that the characters I type in Rasa Shell are displayed properly.
