Хорошо, я нашел что-то странное в URL браузера при открытии TXT-файла с приложением drivenotepad.
URL вроде бы такой
https://drivenotepad.github.io/app/?state=%7B"ids":%5B"1RvRuTWDSUIl1ritooHDWLUtZg0BR3iL-"%5D,"action":"open","userId":""%7D
Его показ, "userId":""
поэтому я ввел свой электронный адрес, как "userId":"xxxx@mygmaildomain.com"
и перезагрузил страницу.
Теперь текстовый файл успешно открыт в приложении drivenotepad с текстовым содержимым.
Также получил успех логи консоли:
