What I have tried

• Add or remove "@CapacitorPlugin" in TestEvent.java
• Calling triggerJSEvent in 2 different ways:
  • As described in official documentation.
    • https://capacitorjs.com/docs/core-apis/android#triggerjsevent
  • Storing a reference of bridge and calling triggerJSEvent from that.
    • https://forum.ionicframework.com/t/capacitor-v3-plugin-addeventlistener-and-triggerjsevent-lacking-and-dont-work-as-described/206641/3
• Both registering & not registering plugin via registerPlugin in MainActivity.java
