The application appear on Sharepoint but can't use it

[Torture13]

Hello,

I made all the steps with success and uploaded the package to Sharepoint Online.
When I try to add the application on my page this message appears on Application catalog.

gdpr-starter-kit-client-side-solution
You can't add this app here.
Find out why

Any ideas?
Thanks,
