Hello! I'm a new app developer using Unity version 2019.1.0f2. I don't know how to build a specific compatible build targeting a Lenovo Chromebook running chrome OS. I was wondering if I can get lead in the right direction. I've set the minimum API Level to Android 4.6 in Unity. I don't know which SDK Tools I'm supposed to be using or NDKs if they are even needed for a build targeting Chromebooks. I've read the Build Settings Documentation and I've seen some changes from 2107-2018.3 where there was a specific button that built the apk's for you. Currently, this option (Build System) isn't available and may be in a different tab or running in a background process that I'm not aware of. I understand that there's an App Bundle option available however I haven't found any documentation on the Chromebook that says "this is how you handle an .aab extension on our end", which has brought me here. I have no experience building apps and if Unity has a way to build a Chromebook app in the version (2019.1.0f2) I'm currently utilizing, that would mainstream the process entirely. Ultimately, I just need a direct file that's compatible to open with Chrome OS. I've tried WebGL but there's no server that I'm uploading the build to so I don't understand how I would open it in a Chromebook. I understand this isn't entirely a Unity concern but knowing what I can do from Unity would greatly be appreciated. Thank you for your time.
