'What type of .ipa build do I need to do to create an app that a customer and distribute through their MDM?

We have an app listed on the iOS App Store but we have a client that wants to instead distribute our app through their MDM so they can control when they upgrade to the next version of our app.

We gave them an exported app store .ipa build of our app to add to their devices using their MDM but when they tried to install and open it they got the "cannot be installed because its integrity could not be verified" error.

They say they can do this with other apps but not our iOS app. Do we have to build it in a different way or with different settings for this to work for them? I confirmed that our profile is not expired.
