How to manually install an app in iTunes 12.7

applicationsinstallitunes

I foolishly installed iTunes 12.7, and now find that I am unable to install a development/QA version of my company's app for testing. After downloading the IPA, I am following the steps found on Apple's support page, under "Manually add items from your computer."

There, I'm told to drag the IPA file to the iTunes sidebar, like so:

Apple's instructions for dragging an IPA file to the iTunes sidebar to install it

But when I do exactly that, it tries to create a shortcut, and fails (the section of the sidebar blinks several times):

Nothing happens when I drag the app; just shows "link" text

This is in iTunes 12.7, to an iPad mini 4, iOS 10.3.3. Manual management is enabled:

Manually manage music and videos option is checked

Have you tried the Apple Configurator 2?

I just read about it here, but haven't actually tried it myself: How do I download an iOS App (IPA) file to my Mac after iTunes 12.7 update?
