getAttachedClients

Get the list of all client applications attached to the user's account.

This method returns a list of `AttachedClient` structs representing all the applications connected to the user's account. This includes applications that are registered as a device as well as server-side services that the user has connected.

It will only return active sessions. For example, if a user has disconnected the service from their account, it wouldn't appear in this list.
