What is the NSExtensionPointIdentifier for this type of extension? Thanks.

Good afternoon, in the video wwdc21-10123 you mentioned your demo application "Homework", where I can find its source code or examples? Thanks.

Good afternoon. I have a question, the answer to which I did not find in the documentation. Let's imagine that there is a parent device and two or more children (each child device received authorization "AuthorizationCenter.shared.requestAuthorization(for: .child)"), an application is installed on each of the devices. All accounts (parent and child) are members of the same Family group. How can I show the familyActivityPicker on the parent device and display information there separately for each of the children's devices. As I see it, familyActivityPicker shows either applications from one of the children's devices or all applications from all children's devices, which seems very inconvenient to me. If you call familyActivityPicker on the application directly on the child's device, then the applications that correspond to this device are shown. If you watch the native Screen Time application on the parent device, there is a choice of children's devices. Thank you!
