Error occurs in the debug console: The icon "cheverondown" was used but not registered.

Steps to Reproduce

and included this in the render():
<Accordion title="Shipment" className={"itemCell"} defaultCollapsed={false}>

Hello World

Submission Guidelines

Start from the Accordion import from @pnp/spfx-controls-react/lib/Accordion and reproduce the issue with the provided render example. Inspect how the default expand and collapse icons are referenced or registered. Done means the Accordion renders with chevron icons without the debug-console registration error.
