This shortcut is sort of a companion shortcut to this one: https://routinehub.co/shortcut/10105/

If you intend to use the above mentioned „major“ shortcut and have a spouse or somebody living with you in your household that you might want to share the shopping list with I recommend you share this shortcut and set up some file syncing between iCloud and Dropbox. Feel free to DM me if you would like help with that.
