How to provide user data deletion request link for Unity Ads SDK

I am trying to publish my app on google play. Unity ads collects some information from users and Google Play’s data safety section is about it. I checked the box where it says Does your app collect or share user data. And then I provided a default link I saw somewhere by Unity where it said Users can delete their data. But a few days later I got an email from google saying the link does not work. Can you tell me how to provide the link or atleast stop the SDK from collecting User Data.
Thankyou
