// With updated threat list 
const myScanner = await Scanner({
		apiKey:  #GOOGLE_API_KEY (required),
		clientId:  #UNIQUE_IDENTIFIER (required),
		clientVersion: #CLIENT_VERSION (optional)
	}, true)

// With default threat list
const myScanner = Scanner({
	apiKey:  #GOOGLE_API_KEY (required),
	clientId:  #UNIQUE_IDENTIFIER (required),
	clientVersion: #CLIENT_VERSION (optional)
})
