Question Question about iOS builds with Unity Cloud Building

Hey all, just had a quick question I wanted to get verified. If I use Unity's iOS cloud building and have an iOS Distribution (App Store and Ad Hoc) certificate attached to the build, does it work such that in order to install the app directly on an iOS device via the share link I need to somehow have the the device's UDID registered and attached to the provisioning profile but I could also submit the build to be posted on the app store and it could then be downloaded by people that way without needing to be registered? (Though I'm not seeing the option to add device to the profile I used which is listed as App Store, so guessing it's only app store?),

I attempted installing the app on a device I haven't registered the UDID yet for and got the following error:


Just wanted to make sure I didn't miss a step or have incorrect information. Thanks!
