How to import test data to Forge app in development stage

I am using Forge CLI and Forge Custom UI to develop a new app.

Is there a way to upload some test data, e.g. via Forge CLI to setup (and reset after some test runs) the Jira Cloud instance where my app is deployed in development stage?

In development for Jira Server or DataCenter you use Atlas CLI. There it was possible to start a local Jira instance and automatically import test data as created via atlas-create-home-zip into this instance.
