Our Tridion Experience space addon extension has a button (let's say 100% copied from the github samples: 'copySchemaItemIdsToClipboardAction'

We need to set 3 buttons there in a group "Setup A, Setup B, Setup C". In the plugin version of classic UI we have a dropdown with 3 options.

Is it possible to implement a dropdown there instead of creating 3 buttons in a row?

Thank you.
