Help changing direct hard-wire to outlet for new dishwasher

I am swapping out an old dishwasher that was hard-wired to a new dishwasher that requires an outlet. As you can see in the picture, the original unit was connected to a cable that goes into the wall.

I was thinking of converting the cable to an outlet by…

1. Strapping the cable to the wall (using a hole strap) and feeding it behind the cabinet to underneath the sink.
2. Connect the cable to a 20 amp outlet (do I need a GFCI?).
3. Housing the outlet in a raised ground electrical box and mount it to the wall underneath the sink.

I would love to get your feedback if this is the proper way to do it and if you may have other suggestions. Thank you!

Edit: The new dishwasher make and model is Beko DDS25842X. I am wondering if it just easier to hard-wire this? I couldn't find any information online if this is possible for this model.
