Web Messaging SDK: Customizing launcher position and colors via deployment config

I’m trying to override the default web messaging widget appearance using the Genesys Cloud JavaScript SDK. Specifically, I need to shift the launcher to the top-left corner and adjust the primary color to match our brand guidelines. The documentation mentions passing a deploymentConfig object during initialization, but I’m unsure of the exact property names for position and colors. Here’s the current setup:

const gcWebMessaging = new GenesysCloudWebMessaging({
 deploymentId: 'my-deployment-id',
 deploymentConfig: {
 launcher: { position: 'top-left' }, // This seems incorrect
 theme: { primaryColor: '#0056b3' }
 }
});

The widget still renders in the bottom-right with the default blue. What is the correct structure for deploymentConfig to apply these visual changes programmatically?
