accessing the unique session id

Every time someone opens the browser and goes to my website there is some unique session id set by Wix. How do I access that session id from Velo code. I looked everywhere for some sample code. I have not been able to find it. I tried the following: console.log( session.getItem(“HS”)); and it says it is null. Also tried ‘hs’. Still the same. I would really like to see some working sample code rather than a link to documentation.
