Freeform is automatically installed as a part of the OS when the iPads are updated to iOS 16.2. Have you checked the iOS release on the iPads?  Otherwise you might want to check if you're restricting any of the built-in apps?

Here is the Bundle ID for FreeForm com.apple.freeform. You can try and manually add it to your Home Screen.

This is another site I use when I am looking for the BundleID of apps so I can add or remove them from the profiles. https://offcornerdev.com/bundleid.html

Hope this helps.
