If by “information you provided” they mean your UCI/File Number, then what this message tells you is that they used these details you provided in your CSE to confirm the status of your application and that is, as they’ve said, “still in process” and the documents you have submitted are sufficient for the time being and no additional documents are required of you.
The message doesn’t hint anywhere that they have just received your documents, nor whether they have or haven’t started any review.
My guess is if you want a more detailed response, inquire whether any of the criminality, eligibility or security criteria have been reviewed or assessed as passed.
