👋🏻 Hi lovely people!
One of our developers has connected JIRA to one of our slack channels by accident. I'm trying to DISCONNECT Jira from that channel (and leave the other channels connected, which have already been setup) .. so I do this..
/jira manage.

then click the MANAGE button .. and it ends up going to a 404 page in Atlassian 
I can't see how I can remove this connection 
Can someone please help?
thanks!
