Why is WebRequest sample not working on some devices which support widgets?

When I try the WebRequest sample from the SDK on the forerunner 55 or fenix 6 simulator it does not work.

It looks like this:

And in the VS Code terminal I see this:

WARNING: fenix6: No supported languages are defined. It's a good idea to indicate which languages you are supporting.
WARNING: fenix6: This is a 'widget' app type but no source code was annotated with (:glance). The entire application will be loaded as a glance process. (glance application)

But on the following webpage it shows that forerunner 55 or fenix 6 do support widgets:

Can someone explain me why it does not work?
