How do add history when creating session/context

[carlosgalveias]

I am doing a chatbot and on the frontend side, I'm saving the conversations I am having. Now I want to resume a previous conversation and I would like to send to my backend the history .
I am cleaning the previous session and context and making a new one, but how do I create it with already a history?

PS: I am using the beta

You can use the conversationhistory parameter when creating a new LlamaChatSession object
