How to hide Adsense to logged in users?

Hello everyone,

It's good to be back, it's been a while since I posted here, hope everyone is doing good,

I would like to know if there's any piece of code missing here,

I would like to hide AdSense auto-ads for logged in users,

But every time I try to wrap Adsense code on this PMPro code they provide, I got an error message on Snippets, and doesn't work at all,

Here's PMPro code:

if ( function_exists( 'pmpro_displayAds' ) && pmpro_displayAds() ) { //insert ad code here }

Can somebody give me a hand here please, I really appreciate
