Is this a statement of something you see as best practice? What is your question? Have you documentation stating that there should be a button on your configuration, but it isn't there? Are you asking on how to create a button to create an Incident task? Is the button there, but do you need to change the conditions on when it shows? 

Also missing info: are you working in a workspace or in the old back end? 

Please, when creating a question on the community, provide information so people can help you and not need to make all kinds of assumptions, causing them to potentially waste their (personal!) time on helping you, without having the proper information to do so.
