If you want to use the ProsodyCtl utility to import certificates, this utility is available (once Peertube is started) using the following command (adapting the path to your Peertube data folder, and replacing "xxx" with the arguments you wish to pass to prosodyctl): `sudo -u peertube /var/www/peertube/storage/plugins/data/peertube-plugin-livechat/prosodyAppImage/squashfs-root/AppRun prosodyctl --config /var/www/peertube/storage/plugins/data/peertube-plugin-livechat/prosody/prosody.cfg.lua xxx`
