how to close onsen ui application on exit?

Question

I am creating a PWA and I need to close the web application when I click on exit. For the same, I have tried window.stop() referencing this and then followed by few issues and queries in Onsen library. I tried

navigator.app.exitApp();

but that too didn't worked for me.

here is my full code

<div class="btn-wrapper">
      <v-ons-button @click="closeApp" class="right-btns send-btn mx-fix">
       Exit
     </v-ons-button>
</div>

and the closeApp function which I am calling

closeApp() {
    this.dialogVisible = false;
    navigator.app.exitApp();
}

Thank you so much for your help :)
