About the QR code displayed after the connection by the Introduction scene of Connect with Unity

Hello Everyone!
I am glad to meet you.

My name is Sadao Tokuyama and I am a web and unity developer.
Let me ask a rudimentary question.

I have run the sample scene in the following article using the unitypackage in version 1.2.0. When connected, the QR code was displayed.

When the QR code is read with a smartphone, nothing happens but a string is displayed. I am unable to proceed any further, how should this be executed to proceed? Please advise.

Best Regards.

Sadao Tokuyama
