Initiation of the journey when an existing user reopens the web bot

We want a solution in which chat history is enabled and upon reopening each time, the user should get the initial message.

The issue is that, when the user again opens the chat widget even after closing the app, the journey doesn’t start all over again unless clicked on the home button or the default journey intent is sent. The user sees the older conversation done on the bot. We are expecting that as we are passing the specific journey slug in the payload, that journey should start automatically for old users as well. Can someone please help with a solution for this?

Why do you want to load welcome message on every load while chat history is preserved?
