Capacitor doesn't work with OneSignal

Hi! I just installed OneSignal Cordova Plugin and the @ionic-native/onesignal, in my first try I followed step by step the official guide of ionic about OneSignal (OneSignal | OneSignal Cordova SDK Push Notification Plugin), but it doesn’t work because in the xCode console throw me back this message as a warning

tried calling OneSignal.startInit, but the OneSignal plugin is not installed.

And obviously in my panel of OneSignal doesn’t detect any device.
After this try, I reed the official doc of OneSignal and Ionic + Capacitor, and I followed those steps (Ionic & Capacitor SDK Setup) instead of Ionic doc. Now the warning that I got is this:

2021-09-09 20:19:40.146713-0400 App[50104:1022578] WARNING: appId set, but please call setLaunchOptions(launchOptions) to complete OneSignal init!

And the issue is the same, I cant see any of my devices connected in OneSignal. Please I need help.

This is my Ionic info:

How did you install the plugin? Did you run npx cap sync after installing it?

I just ran the followed commands:

npm install onesignal-cordova-plugin
npm install @ionic-native/onesignal
ionic cap sync
