hey guys, #MCP support is freaking awesome... however, i am having trouble finding a way to pass additional call/session/metadata to the MCP server.... when calling from a phone number, it does pass this info to the MCP server, but only on tool calls, not when retrieving tool list... and then for embeded widget/client sdk, i cant seem to create a call with a sessionId or any information that will also be provided to the MCP server. Looking to pass along authentication somehow
