/**
 * React hook for using a Live Share `LiveFollowMode`.
 *
 * @remarks
 * Use this hook if you want to add the ability to follow specific users or let a user present to everyone in the session.
 * Each user has their own `stateValue`, which is the value other users will reference when that user is presenting or being followed.
 * The `state` response includes the user's `value` that the local user is "following", whether it be their own or someone else's.
 * This hook can only be used in a child component of `<LiveShareProvider>` or `<AzureProvider>`.
 *
 * @template TData Optional typing for the custom user presence data object. Default is `object` type.
 *
 * @param uniqueKey The unique key for `LiveFollowMode`. If one does not yet exist, a new one will be created.
 * @param initialData The initial value for the local user's `stateValue`.
 * @param allowedRoles Optional. The user roles that are allowed to present to use `startPresenting()` or `stopPresenting()`.
 * @returns `IUseLiveFollowModeResults` results, which contains React stateful objects and callbacks.
