When I use the Samsung File app to create a short-cut as a menu option when it opens the file (Google Sheet) is in View Only mode. This is a local file NOT on Google Drive. The sheet file is stored in my Local Document folder, I can click it from the File app and it opens as View Only, the only way I can edit it is to open it with Sheets.
Since this is a "sheets" file, it stands to reason that only Sheets will have full access to this file. Try contacting Google to see the proper way of doing whatever it is you are trying to do.
