Can we use the header button (workflow button) to enter edit mode? I have tried

instance.web.FormView.include({

        init: function() {

            this._super.apply(this, arguments);

        },

        events: {

            "click .resume_consultation": "resume_consultation",

        },

        resume_consultation : function(ev) {

            ev.preventDefault();

            ev.stopPropagation();

        }

    })
