WHY IT NEEDS A POLICY

Why setMultiAssetsMode needs a policy

The tool name 'setMultiAssetsMode' strongly implies changing account-level trading settings (multi-asset margin mode) on a cryptocurrency futures exchange. This is a Write operation that modifies account configuration. The incomplete description ('Change user') reduces confidence, but the name clearly indicates a setting/mode change rather than a financial transaction.
