CRM Lead/Opportunity how to add defined follower automatically
I would like to add automatically a Channel as follower when a new lead is created. My idea is to do it with a new Server Action, but I am not sure whether this is the right approach.
So I created a new Server Action under Technical Settings with following parameters:
Action to Do: Add Followers
Add Channels: Sales
But this is not working (Odoo12)! What's wrong? What can I do that this Channel will be added automatically while creating a new Lead/Opportunity?
