Channel event-elasticsearch

can you suggest me how do can I get the url(sitemap) of page being published through channel-manager? For event category “channel-manager” and event action “publishMount”.
I am intregating my bloomreach app with elasticsearch. So when a channel is publised I need to get somehow the path of page that has been modified,do you know how?

The event should contain the user ids of the users whose changes will be published. The nodes in the preview workspace that are affected should have a property hst:lockedby. I haven’t tried this myself, but the answer should be somewhat in that direction.
