Jitesh Gaikwad’s Chatbot Widget displays messages sent by the server in sequence with pauses of 5 seconds or more, all together as if the server had sent a single message

Hi everyone, I’m using Jitesh Gaikwad’s Chatbot Widget with Rasa OpenSource 3.4. I have 3 custom actions in sequence that each take 5 seconds to process and send a message to the user. In the Rasa shell, the messages arrive correctly 5 seconds apart, whereas in Jitesh’s Chatbot Widget, they all arrive together after the last custom action, i.e. after 15 seconds. It seems that the messages are only displayed on the screen when the server sends an action to listen for user input. How can this Widget behavior be corrected? Thanks, Biagio.
