1. Gain access to the Discord channel where OpenClaw interacts
2. Monitor bot messages to identify pending approval IDs
3. Capture the exact format of approval requests
4. Document the structure of /approve commands

1. Run the PoC script with the captured IDs
2. Send the decision (allow-once or allow-always) along with the parameters
3. The bot processes the command without validating user permissions
4. Approval executes successfully

If the Discord text approval triggers automatic functions on the server:
