Easiest Way to Use Bixby to Add Item to Google Tasks?

[Jon44]

I think Bixby is great. The one frequent "chore" I do with my phone that it hasn't been the best on is quickly adding an item to my grocery list, which I manage with Google Tasks (this is one thing Google Now does well, where you can just say "Note to Self: Eggs").
With Bixby, "Open Tasks" works, but I can't figure out how to have it automatically add an item. I figure if I can come up with a long sentence that works, then I can create a voice shortcut for it...
Any suggestions appreciated.
