```

## Parameters

- `size`: The size to use when looking up the action icon.

## Return Value

## Discussion

Discussion This icon should represent the extension in action sheets or toolbars. The returned image will be the best match for the specified size that is available in the extension’s action icon set. If no matching icon is available, the method will fall back to the extension’s icon.
