Embedded chat is broken on help page

Hello support & doc team,

dunno if this post will be any useful, but the embedded support chat in there : https://yunohost.org/#/help

has been broken for quite some time now (I think since freenode implemented some antispam tactics, or maybe us putting +S on the irc to fight spammers ?)

I won’t have time to look into it before ~November so any help investigating workarounds / alternatives is welcomed :s
