I use Odoo 14.0 .
I created a chat channel for all my Odoo users.
Still, not all user can see this channel, and I do not find an add user button in the channel administration.
says that with some SQL magic I could solve this but I do not have access to the database. And at all, this should be an easy thing to manage the users of a channel.
How can I do this in Odoo?
