iPhone apps won't install on iPads using Apple Business built-in device management

We were setting up Apple Business built-in device management. All went well until we tried to install a couple required iPhone apps on the iPads. These apps install and run fine without device management. But the built-in management will not install them on iPads since they are iPhone apps. I hope this changes since they are required for the operation of our business and there is no iPad-specific version of them. Anyone have a workaround?
