Can a market place app create an action for automation!

Hello everyone,
I’m developing an app that can be used by pipedrive users. I want my app to have actions available in automation, similar to how Trello or Asana integrate with automation workflows. Is it possible for third-party apps to create automation actions in Pipedrive, or is this feature restricted to Pipedrive only?
Please clarify.If it is possible, could you provide me with the documentation link?
Additionally, in my sandbox account, I’m unable to create an automation as it’s asking me to upgrade.
