[CRM9.1] Unable to set stage on opportunity

var entityFormOptions = {};
        entityFormOptions["entityName"] = "opportunity";
        entityFormOptions["selectedStageId"] = "D3CA8878-8D7B-47B9-852D-FCD838790CFD"; //it's an id of 3rd stage
        Xrm.Navigation.openForm(entityFormOptions).then(
            function (success) {
            },
            function (error) {
                console.log(error);//no error here
            });

Xrm.Page.data.process.moveNext( function(val) {console.log(val);});

// all required fields must be filled so it's not for me

Xrm.Page.data.process.setActiveStage("6b9ce798-221a-4260-90b2-2a95ed51a5bc", function(val) {console.log(val);});

//It kind of works but when it prints "success" then whole process flow stays at same stage:

//Xrm.Page.data.process.getSelectedStage().getId() and Xrm.Page.data.process.getActiveStage().getId()

//says that correct stage is selected but... yeah
