As per the design we need to follow the below process
1: we launched the company portal from Self service
2: It invoked the company portal in registration mode, means after entering the credentials device will register to Azure Ad and will store the wpj cert to key chain.
3: now jamf AAD will launch, unfortunately we closed the pop-up (jamf add) or something wrong happened with the system or browser at that point of time did not respond, thus it did not complete intune registration
Now my question is how we can Identify, how many such devices we have in out infra which missed step 3
