Chatbot - browser refresh

Hi, There

I am new to dash it’s been 3 months since I started using it. Recently I built a chatbot using dash framework. Everything works fine with received messages and bot responses. But when I refresh browser or close the chatbot tab and if I open again with the link that dash gives me I can see still earlier conversation history. Would you please let me know how can this get sorted out

I found the answer for this …and its working perfectly with no issues…
