e.force:navigateToSObject sample code

e.force:navigateToSObjectDemo.js

createRecord : function (component, event, helper) {
    var navEvt = $A.get("e.force:navigateToSObject");
    navEvt.setParams({
      "recordId": "00QB0000000ybNX",
      "slideDevName": "related"
    });
    navEvt.fire();
}

I have tried the above code and I found that the value for attribute"slideDevName" is not working. No matter what we give there[details,related] it's just navigating/refreshing the page.

hi if you implement it in the lightning experience or mobile 1

I am doing in lightning experience, but it is still not working. Do we need to add any particular interface in component?

I also tried and it did not worked for me. Please suggest if anyone found a way to work with navigateToSobject related tab.
Alternative is the navigateToRelatedList component to go to the "Attachment" related List.
handleClick : function (component, event, helper) {
var relatedListEvent = $A.get("e.force:navigateToRelatedList");
relatedListEvent.setParams({
"relatedListId": "CombinedAttachments",
"parentRecordId": event.target.id
});
relatedListEvent.fire();
}

"You can set a specific slide in the Salesforce app, but not in Lightning Experience."

Please refer to this site: https://developer.salesforce.com/docs/component-library/bundle/force:navigateToSObject/documentation

I also wanted to use "related" but I just found out this today.
