Detect hardware back button press when using only capacitor (without ionic)

[iarkaroy]

I have added capacitor to my existing vue app. Looking for a way to detect hardware back button to close the app. Tried adding event listener for ionBackButton but it is not working. I suppose that event is fired in an ionic app (which it is not). Can anyone please guide me how can I detect hardware back button? Please note that I did not initialised an ionic app from scratch. I have added the capacitor cli, core and platforms (android and ios) on top of existing vue app.

Thanks

I think you're looking for the backButton event in the App plugin: https://capacitorjs.com/docs/apis/app#method-addListener-3

Yes, this is what I was looking for. Thanks.
