Upload LOB mobile app to Azure Intune programmatically

I am trying to add a mobile app to my Azure Intune tenant programmatically. I can upload the metadata for my app to Intune, but I cannot upload my app binaries, and as a result, I cannot install this app on the enrolled device. I understand that after creating the application metadata, I have to download the application binaries and commit them with the / commit endpoint, but I cannot find information on how to do this.
