How do you remove someone from a group text. The swipe left and delete does not work.

Every "how to" on removing someone from a group text says tap on info and you get a list of the contacts. Then simply swipe left to get the delete button to delete them. It does not work. There is no Delete button. In the comments there are several people saying it does not work for them.

So my question is...How do you remove someone from a group text on iPhone. I am on an iPhone 6+ using iOS 12.1.4
