To make it easier to get started with Admin Buttons, there are now button templates in the app to support many common merchant use cases, with more being added all the time. Simply click "use" on a button template, set it to "active" and save it.
We've also released corresponding Flow templates using custom Admin Buttons triggers for each button. The button template handles what your store team sees in admin. The Flow templates handle the workflow steps. Once you've installed both templates and have them working, you can customize them for your own store's workflows.
