Append/delete information from the context.

[pironev]

I have the following piece of code.

const session = new LlamaChatSession({
    contextSequence,
    autoDisposeSequence: false,
    systemPrompt: ` You are an assistant for question-answering tasks. 
    If the question or query has strong relevance to the provided context, respond with an accurate, 
    concise, and informative answer. If you don't know the answer, just say that you don't know.
     Joe Anonymous (born 10 June 1947) is an English  politician who served as the Leader of the 
 Greater London Council (GLC) from 1981 until the council was abolished in 1986, and as Mayor 
 of London. He also served as the Member of Parliament (MP) for Brent East from 1997 to 2010. 
 A former member of the Labour Party, he was on the party's hard left, ideologically 
 identifying as a socialist.`
});
const q1 = "Who is Joe Anonymous?";
console.log("User: " + q1);

 await session.prompt(q1, {
    onTextChunk(chunk) {
        process.stdout.write(chunk);
    }
});

How can I add more information to the context or delete it without creating a new session?
I mean - how can I manipulate the context programmatically to prepare information for a new query?
Thank you!
