Sandbox/Testing Coinbase plugin

Hello Team,

I have installed the plugin and integrated successfully with woocommerce on local environment.

It would be really helpful if I get someway/steps to test the payment flow using dummy coins or something like sandbox environment.

I was not able to get the information so if someone can redirect me the documentation or help page that will be very helpful.

The page I need help with: [log in to see the link]
