Onion soup powder?

[Pigleychez]

Ive seen a recipe on Pinterest that id like to try. togetherasfamily.com/2017/11/slow-cooker-asian-sesame-chicken/
Its ingredients include Powdered Onion Soup but ive really struggled to find any. The only onion soup I could find was a tin of French Onion.

Could I use this instead do you think?

I wouldn't use tinned soup in place of powder - but what about this?

You can get it from Ocado OP: Maggi onion soup mix.
