How to check Token usage in Antigravity Hooks

Is there a way to retrieve the number of Input Tokens, Cached Input Tokens, and Output Tokens for chats executed via Hooks in Antigravity (CLI / 2.0 / IDE)?

I checked the transcript.jsonl file located in directories like .gemini/antigravity-cli/brain, but this information was not available. While I could estimate the token count by checking the character count since the chat content is visible, I would like to get the actual token usage data. Additionally, I was unable to find any OpenTelemetry related settings or logs in Antigravity, which were previously available in Gemini CLI.
