how to run client local app from Linux hosted xojo web app

Targets Web

First of all, I am using MacPro (mojave).

I came to the point that I need to run the client installed app from my xojo web app hosted on remote server.
Looks like “URI” is the solution.

I found XOJO BLOG post from but I got hard time to simulate it and unable to make things functional.

I also tried to follow the video presented by the author but ended with another question as shown in the photo.

I hope somebody can provide me a clear cut on how to implement this solution.
A share of sample xojo app will be better for my better understanding.

The blog post is about a custom url handler on the Mac. How does this relate on starting an app on Linux?
