Drilling out carefully is the answer.
Those little screw stubs look too skinny to be grabbed by an EZ Out or similar broken screw extractor.
Start by drilling a very thin hole, as near to center of broken screw as possible.
Then go up slightly in bit size, and use side pressure as needed to improve centering of the bit in broken machine screw stub.
You might need to use three or four different size bits.
The holes you are left with might be able to receive new machine thread screws.
You can sometimes use a few sacrificial screws, to clean out the threads of the hole, then toss those screws.
But the holes might be too rough and raggedy, so you might end up needing to just force in some stainless sheet metal screws, just a whisker wider than the drilled holes.
