How can I import 384 historical records into an existing KoboToolbox project?

Hello Kobo Team,

I have a deployed KoboToolbox project:

Project UID: atZMpNqvDkpbsahDbmkWbA
Form ID: 3780849
Deployment UUID: b2b2489854e7497cbf24d0e02419d207

I already have 384 completed survey records in CSV format.

I successfully connected to the Kobo API and can read existing submissions through:

https://kc.kobotoolbox.org/api/v1/data/3780849.json

I converted my CSV records to XML matching the deployed XForm structure.

My goal is to import the 384 historical records into the existing project so they appear in Data → Table, Reports, and Downloads.

Is there a supported KoboToolbox method (API endpoint, OpenRosa endpoint, or backend process) for importing historical submissions into an already deployed project?

Thank you.
