After logging into Google Drive and clicking "CREATE", you can select an app like Document, Presentation, or Spreadsheet to create a file. You can connect more apps by clicking "Connect more apps" at the bottom of the app list. This will allow you to see additional apps and select them. Once an app is selected, you can create a new file and give it a name without needing to manually save. You can then share the file by changing the share settings, inviting group members, and clicking "Share & save".
