INtune config | web filtering for iPads iOS devices

Description

I have iPads enrolled successfully as corporate devices in my tenant. I also have defender for endpoint. I have defender for endpoint app pushed to all test iPads successfully.
Defender for endpoint is successfully blocking adult content, gambling and specific sites like spotify, on all windows laptops in both Chrome and Edge.
But adult content, gambling are not blocked for iPads safari and chrome browsers. Strangely though, spotify is blocked!
I need someone to help me configure:
1. block all adult and gambling content for iPads2. ENABLE google safesearch3. Block categories of stuff for iPads, e.g. social media, violence, innapropriate content etc
The tenant is for a school, so I need to be able to block all nasty adult content, gambling and whatever categories I want. I have it working perfect for Windows devices in Intune, but for iPads, it's just not working.
