[SalesForce] Can lightning:navigation be used in Communities

I am trying to implement a navigation mechanism for my community

So I am trying to implement the new lightning:navigation component.

This is my component – main:

MARKUP

<aura:component implements="forceCommunity:availableForAllPageTypes,flexipage:availableForAllPageTypes,force:appHostable,lightning:isUrlAddressable">
    <lightning:navigation aura:id="navService"/>
    <lightning:button variant="base" label="Open page" title="Click to open page with queryString attributes" onclick="{!c.handleClick}"/>
</aura:component>

CONTROLLER

({
    openPage: function(component, event, helper) {
        var pageReference = {
            type: 'standard__component',
            attributes: {
                'componentName': 'c__main'
            },
            state: {
                type: 'open',
                id: 'a1ZW0000001Pc95MAC'
            }
        };
        var navService = component.find("navService");
        navService.navigate(pageReference);
    }
})

When I add this component to lightning experience from the app builder, the navigation happens good and I get the url of the component + the 2 attributes of the queryString.

But when I add this component in my community – a click on the button does not do anything.

QUESTION

Is lightning:navigation supported in Salesforce Communities?

If it is – what am I doing wrong?
