If you have a field referencing a URL you can include a button on the Board view. Just add the URL field and chose the option to display it as a button. If you want to restrict which column it is appearing in, you could use a filter and/or a filter in combination with some conditional logic and formula fields to further restrict when URL button fields show up. Not sure where in your example you want buttons to show up?

Thanks Peter, I want to show the button just below “due date”
