Enterprise EAS Build Error - Unable To Install App This app cannot be installed because its integrity could not be verified

We have an organization of about 500 employees, and we have developed an app for internal use only. I want our employees to use this app.

So we have built the app ( we choose EAS build CLI with all valid certificates, provisioning profile and unique bundleIdentifier)

Then, we got a link which we can open on our iOS devices (or scan the QR code) and follow the instructions to install the development profile.

Then we got a link to download an application on our device. And it seems an app icon in our device but when we try to open it by touching the icon we are getting a message "Unable to install App, This app cannot be installed because its integrity could not be verified."

In short we can say ,Our organization is facing the following error when downloading an "enterpriseProvisioning": "universal" EAS Build app from Expo.
