Problem with transfering local files to Azure InterSystems Instance

I recently set up InterSystems in the Azure cloud environment. So far, no issues. Recently, I was tasked with uploading the IRIS.dat file (FoIA VISTA) into the instance. I was guided by my teammates to do the following: System Administration > Configuration > Local Databases. The problem is that I need to transfer the .dat file to the instance, because, as it is running on a local machine, it cannot retrieve files from my local drive.  Is there a reliable solution, such as a transfer method or way of using the Web Gateway endpoint, one can provide to assist? Thank you for your time.
