Getting the following error when trying to run the example:

The only modifications I have done us changing the clientId value to match my torus/google application and commenting out a parameter in TorusDirect.init which seems to be missing in the library's implementation:

        // browserRedirectUri:
        //     Uri.parse('https://scripts.toruswallet.io/redirect.html'),
