An openai Agents SDK returns total agent’s loop tokens usage object as:

```auto
inputTokens,
inputTokensDetails: [{cached_tokens}],
outputTokens

```

so, here the inputTokens are all input tokens, including cached and uncached, or only uncached tokens?  
Is it correct to calculate uncached tokens as `inputTokens - inputTokensDetails.cached_tokens`
