Load rive file from custom location

I'm using the iOS SDK v6.1.

In my app I'm downloading a rive file from a remote server. However creating a RiveViewModel with a name tries to load a bundled .riv file. Is there a way to use a custom file path to load the file?

Alternatively I can also let the SDK handle the download and initialize the view model by using RiveViewModel(webURL:) . However this initializer doesn't seem to have the customLoader to replace assets in runtime. Additionally using this initializer crashes with main (1): EXC_BAD_ACCESS (code=1, address=0x20) when trying to configure it:

    struct MyArtboardView: View {
        let viewModel: RiveViewModel

        init(viewModel: RiveViewModel) {
            self.viewModel = viewModel
            do {
                try viewModel.configureModel(artboardName: "myArtboardTitle")
            } catch {
                Logger.log(.error, "Rive: \(error)")
            }
        }

        var body: some View {
            viewModel.view()
        }
    }

This does not crash when using a locally bundled rive file and using the fileName initializer.

So my question is: Is there A: a way of using a custom path to load a local rive file, or B: a non crashing way of loading a rive file using webURL that also allows for a AssetLoader closure.
