Google Ads on within free Listings

Hi everybody!

I want to add Google ads to all my free listing descriptions (actually inside the description, not a widget), I was adding the code to each listing created but I have noticed that the ad block created for this has been removed :(, Google obviously didn’t like this.

Is there a way that I can add ads, a plugin or some other solution, that will not be removed by Google?

Thanks for your help
