Submit my App to non Company Devices

Hello,

i'm new in Apple Development and have a question about submiting my app to the App Store. First of all the app is only for employees and partners of our company. But the Apple Devices are personal Devices of our Employees. How can i publish the app without to much work? I know there is the Apple Business Manager service, but does it work with non-company devices?
