Notes

1. Launcher supports the following variables, some of it will be set internally according to the API

- config-state (internal)
- qr-options (internal)
- embed-type (internal)
- product-id
- scene-product-id
- variation-id
- variation-sku
- ar-mode
- show-ar-banner

2. There is a known issue where the QR Code does not render properly when not full-screen. This might be an internal layout issue and needs to be looked into
