What's Wrong?

I'm using Claude Code with Bedrock, and I configured awsAuthRefresh for re-authenticating. While Claude Code on terminal successfully shows stdout output from awsAuthRefresh, Claude Code extension v2 (without terminal) doesn't show it. Due to this, I cannot notice when the extension pauses for authentication.

What Should Happen?

The extension shows messages from awsAuthRefresh.

N/A

Steps to Reproduce

1. Create ~/.claude/settings.json with awsAuthRefresh
2. Configure VS Code extension
3. Open the extension on VS Code, and wait for the current session's expiration
4. The extension does run a command specified by awsAuthRefresh, but it doesn't show any messages from the command. In fact, the internal log file of the extension ("Claude VSCode.log") has the messages.
