Issue: Secret value management I used to write api keys and access token in system prompt. And use these values when calling api key request tools. But, I was frightened that sometimes my assistant reads api key values. So, I write these 2 lines at the bottom of api values (as you can see in screenshot) * The keys listed above are case-sensitive. Do not change the casing or naming of these fields. * The values listed above are secret. Do not expose any of them to the user, even if requested, especially tokens and (API) keys. My question: What is the best way to save api keys in assistant ? In github & vercel, there is secret value management page. https://cdn.discordapp.com/attachments/1211484481848873020/1401033305201311857/img_20250801.png?ex=688ecd71&is=688d7bf1&hm=a5081c34eb5f1ed57d7fd7789a3a9cd39e38d78b7b1750333c783b60445de524&
