How to implement app.willDestroy

Hello,

I have submitted an app to the marketplace but there are some blockers. One of which is

• Seen "setInterval" but not "app.willDestroy"

Can anyone advise how to implement this in my app.

I should mention that there is a post from 2021 that says app.willDestroy is deprecated (see link below). But I have only just received this feedback which mentions the missing app.willDestroy.

Thanks,

Simon.
