Is the Ukrainian refugee your parent, or your spouse's parent? You did not say that in your original question. If the person is not your parent, the blog post that you found is not a direct answer to your question. The blog post is about claiming an elderly parent as a dependent. In particular, your parent does not have to have lived with you to be claimed as a dependent. But to claim someone as a dependent who is not your relative, they must have lived in your home for the entire year.
