Microsoft Intune Company Portal for Linux and Conditional Access Issue

When I look in User sign-ins (non-interactive), I can indeed see Failures against "Microsoft Intune Company Portal for Linux", because I have a policy that requires MFA for all resources. Problem is I can't exclude that Portal for Linux, as it doesn't show up a resource.

How do I make this work, I can't exclude users from that CA policy, as that would remove their MFA requirement.  Is this still an outstanding bug?  Feels like a bit of a flaw at the moment.

Since this problem still exists at least 2 years later, I feel Microsoft aren't fully supporting Linux as device type in Intune, unless the resource I actually need to exclude is different name, but no documentation is pointing me towards this online. Both official docs or various blog posts.
