I have my first three watch faces live in the Play Store. I was thinking about making companion apps for greater discoverability. I have minimal experience coding java or kotlin, so I want to keep the apps as basic as possible. I’ve seen popular posts in this forum with guidance on how to make these apps, and a lot of discussion around a “download” button. My main question is what kind of functionality I should build into the phone app to ease installation on the watch. Looking through documentation from Google and it seems like just installing the companion app on the phone should bring up a notification on the watch, without me having to code anything for that.

“Distribution to Wear watches
On devices running Wear OS, when a user installs a phone app that has an associated watch app, the user gets a watch notification about the available watch app. Tapping the notification opens the watch Play Store, giving the user the option to install the watch app.”
Is my understanding correct? I can basically make a one-screen phone app that presents some information, and the watch will receive an installation notification? As long as the app is named and bundled properly, of course.
