How to change text of 'read more' of services widget in business template?

Hi there,
I can’t find the location in the editor where to change the ‘read more’ text into a Dutch translation. I’ve changed it in several files, but I still see the ENG text.

I’m talking about the read more links that are displayed by default in the services widget of the business template like is explained here: https://themegrill.com/theme-instruction/spacious/#businesstemplate

I can’t show my site yet, as I’m working on a local machine, not published anything yet.
