Slow cook beef brisket slices method

What’s the best method for cooking beef brisket slices? I see tons of recipes for the full brisket, but I only have a couple of slices that are about an inch thick, and 9 inches long,total weight 800 grams with no bone.

I am planning to do them in the slow cooker for 8 hours on low, salt and pepper, paprika, half an onion sliced, and some chicken stock to half cover the meat, sort of like a braise.

Would love some advice from anyone!
