Is it possible to use ChatHistory with a VolatileMemory store?

[sannyg0701]

Hi. I have just begun playing around with SK and I have been able to set up a volatile memory store using the tutorial from here
https://learn.microsoft.com/en-us/semantic-kernel/get-started/quick-start-guide/memory-and-embeddings?tabs=Csharp and I have been able to set up ChatHistory from here https://learn.microsoft.com/en-us/semantic-kernel/get-started/quick-start-guide/context-variables-chat?tabs=Csharp.
Is there a way we can combine the two?

Here is what I have so far

await _semanticKernel.Memory.SaveInformationAsync(MemoryCollectionName, id: "info1", text: "My name is Andrea");
await _semanticKernel.Memory.SaveInformationAsync(MemoryCollectionName, id: "info4", text: "I visited France and Italy five times since 2015");

var query = Console.ReadLine();
var results = await _semanticKernel.Memory.SearchAsync(MemoryCollectionName, query).ToListAsync();
var variables = new ContextVariables(query)
{
    ["context"] = results.Any() ? string.Join("\n", results.Select(r => r.Metadata.Text)) : "No context found for this question.",
    ["input"] = query,
    ["history"] = history
};

var result = await _semanticKernel.RunAsync(variables, _semanticKernel.Skills.GetFunction("AskPlugin", "AnswerQuestions"));
history += $"\nQuestion: {query}\nAnswer: {result}\n";
context.Variables.Update(history);

Console.WriteLine(result);

My prompt is as follows

Use the following pieces of context to answer the question at the end. If you don't know the answer, don't try to make up an answer and answer with 'I don't know'. Answer in the langauge that used for the question.

{{$context}}

Question: {{$input}}
