beforeinstallprompt doesnt get fired in +layout.svelte

[rheanV]

I have an installable PWA (for sveltekit app). I want to add a custom button for installing the app. I placed my window.addEventListener('beforeinstallprompt', (event) => { event.preventDefault(); //logic }); in the onMount of the +layout.svelte file. I have all other configurations correct, meets all installation criteria, and can be installed via the browser download option in the URL bar. However, my "beforeinstallprompt" does not get fired in the +layout.svelte. If I place it in app.html then it is fired but not in +layout.svelte. How should I fix this? What am I missing in my sveltekit app setup?

Same issue here. I want to use window.addEventListener('beforeinstallprompt', (event) => { event.preventDefault(); //logic }); in order to hide/show prompt to install PWA. It seems right now there is no solution for it.

I'm doing the same thing in a +page.svelte, it fires haphazardly around 5% of the time. Not sure what the solution is right now.
