Ionic App `appRestoredResult` Doesn't Fire

Question

I am building an Ionic app that uses the camera plugin, and I am having problems with getting the data to come back from the camera. As the Capacitor docs on the Camera plugin (In the paragraph above the variables section) say, the app will sometimes be "terminated" in the background and so when it returns to the app, you need to listen for the "appRestoredResult in the App plugin" to get the camera result. The problem that I am having is that this event never seems to fire.

I added listeners for the following events: backButton, pause, resume, appRestoredResult, and appStateChange.

backButton works, and shows the toast notification (which is what I was using to test to see if the events were fired).
pause seems to only be fired if I press the "home" or "opened apps" button (the ones on the phone, not part of my app).
resume only fires when I return to the app after the pause event successfully fired. This event should also fire when I come back from the camera as well, shouldn't it?
appRestoredResult doesn't seem to fire ever. Which it should fire after returning to the app after the camera (if the app was terminated during the picture taking).
appStateChange fires when I pause or resume the app.

What am I doing wrong?

With a little more digging and a little more testing, I figured out the problem.

The reason why appRestoredResult event isn't firing, is because it only works with a specific camera library (which I had switched to previous to see if I could get that to work, but then I started using these events, and didn't switch back).

This is what I had previously

...
import { App } from "@capacitor/app";
import { Camera } from "@ionic-native/camera/ngx";
...

This is what I have now

...
import { App } from "@capacitor/app";
import { Camera } from "@capacitor/camera";
...

So if you are having trouble with the appRestoredResult event not firing, check your libraries and make sure you are using both from @capacitor.
