Changing "Added to cart" to other language in Fashe theme

When I add a product from my collection page into my shopping cart I get a pop-up message saying ‘Added to cart’. However this is not in the language the rest of my website has.

I can’t seem to find where to edit it.
It is not just a regular language edit, as I have already done that and it has worked for the rest of my website.
The problem is just with this pop-up message.

If somebody has the answer, please share it if you like.

Cheers!
