You have to be approved by Google first, in order for it to work.

To do this:

1. Send your validated schema-containing email to a special google email address (use this tool: https://www.google.com/webmasters/markup-tester/u/0/) ... then:

2. Fill out the "Gmail Schema Whitelist Request" form that describes your website and what you intend to do with the one-click action. Here's the form: https://docs.google.com/forms/d/1PA-vjjk3yJF7MLPOVKbIz3MBfhyma2obS8NIZ0JYx8I/viewform?pli=1&fbzx=-1177483801701354615
