I'm a little confused about scopeViewModel

[est7]

We already have ScopedRetainedActivity, it can be written as:

val  module = module {
    scope(named<ScopedRetainedActivity>()) {
        scoped {
            MyViewModel(get())
        }
        scoped<Repository> {
            RepositoryImpl()
        }
    }
}
class ScopedRetainedActivity:RetainedScopeActivity(){}

Why is there a ScopeViewModel? Shouldn't a ViewModel not be consistent with the lifecycle of a RetainedActivity or Fragment? Or is it that the ScopeViewModel maintains a smaller lifecycle scope here?Or sometimes, when we ourselves maintain a ViewModel with a longer lifecycle through ViewModelStoreOwner, should we use this ScopeViewModel?
