How do I find a family member's App purchases in our Family Sharing plan?

Hi,

I am trying to see all the Family Share charges my adult children are doing for subscriptions, Apps and in-app charges. I can't find a complete list. The alternative is to turn off family sharing, but that's a shame.

I have already done the below:

1. Go to the App Store app  on your Mac.
2. Click your name in the bottom-left corner (or click Sign In if you’re not signed in).
3. Make sure you sign in to the same Apple Account you used to purchase your subscriptions.
4. Click Account Settings at the top of the window, then sign in again if necessary.
5. In the Manage section, click Manage next to Subscriptions.
6. Click Edit (if you have more than one subscription),

Then go into each family member (but details and charges aren't in there, as well as a lot of other things.
