          modelType: string;
          usage: {

          }
      }
  };

const usage = getLLMTokenUsageForSession();

if (usage) {
  Object.entries(usage).forEach(([key, info]) => {
    console.log(`Model: ${info.llmDisplayName}`);
    console.log(`Provider: ${info.providerType}`);
    console.log(`Type: ${info.modelType}`);
    console.log(`Input tokens: ${info.usage.inputTokens}`);
