There is no call ID to give. I'm saying when I use the API to patch a tool, assigning custom headers, I see them appear in VAPI's UI, but they're not appearing in the response of a HTTP Get request using the '/tool/' endpoint. Are you guys doing that on purpose and storing them encrypted on a DB, using a separate fetch to get the info and populate it, or should/will they appear in the response of a get tool request?
