@Manafpm1 , Missing commerce-events-ext-tpl is fine. You can choose any generic action template and change the code accordingly. The commerce template just installs additional dependencies, that can be manually done from generic scaffold.
But for unable to listen commerce events, suspecting permission issue. Your project must listen to commerce events, only then your action gets invoked. Speak to your admin to grant developer access to AppBuilder and Commerce. And check with your admin if they see the option. Its one time setup, fine if admin registers on your project.
