Using Flying Scripts is not difficult at all, you just need to know the keyword of the JavaScript that you want to delay and that is it.
If you want to get a perfect Google Page Insights score, you can delay the execution of the Adsense Ads JavaScript
You can set the timeout to never and the ads will show until there is user interaction.
User interactions is defined as events from the user like mouse hover, scroll, keyboard input, touch in a mobile device, etc.
I have used Flying Scripts to delay adsense ads and I get perfect scores in Google Page Insights and I haven’t noticed a decrease in earnings.

Flying Scripts: Common Questions
These are some common questions about the flying scripts plugin:
Can we delay scripts added by CloudFlare?
Scripts such as email-decode.min.js injected by CloudFlare proxy are added after Flying Scripts has processed HTML. So they can’t be delayed using the plugin.
Can we delay scripts added by Ezoic
Scripts such as nmash.js injected by Ezoic proxy are injected outside of WordPress so flying scripts can control them
