The kokoro checks seems to be failing on unrelated changes of this PR

Your PR is modifying a few go.mod and go.sum files outside the scope of your change, which is running these failing tests. If you limit this change to files under securitycenter, these problematic tests will not be run, and your tests will pass.

These files were modified because of some previous checks failing. The suggestion command from that (after I ran) created these modification on the files.

Should I revert these files all together ? ( I'm new to development in golang + sample)

Yes, please revert the go.mod and go.sum changes outside of securitycenter. It is generally sufficient to run go mod tidy in the directory where you make changes, to update the nearest set of go.mod and go.sum files. (this is usually not a problem, but there are some pre-existing broken tests that need to be fixed...)
