This isn't a huge deal, states routinely allow civilian and media witnesses to observe executions. it is a volunteer process usually. Viewing this Livestream will be a volunteer process. I doubt it will be graphic, and perhaps there will be an age check.
Also lots of folks now like to claim they are citizen journalists, auditors, etc.... well now they are getting that chance on a mass scale. Go watch the process if you like or not. This isn't compulsory viewing.
