Improve live example by replacing all window.alerts by toasts or other non blocking alerts

[danielcaldas]

Is your feature request related to a problem? Please describe.
Currently, there are a few window.alert usages in the live example that might be a bit annoying for the end-user because although in fact an action was performed, it does not mean that we need to interrupt the browser.

Describe the solution you'd like
Provide the interaction example messages in a nonblocking notification component such as a toast or a notification banner. A good candidate for this kind of use case is fkhadra/react-toastify, but others might come into play.

Describe your use case
User clicks on some link, informative toast is display for demonstration purposes.

Describe alternatives you've considered
fkhadra/react-toastify

Additional context
This is ugly.
