Disable Watchr's default email notifications

In our use case, the agents becoming Watchrs do not have an active role in the ticket resolution, they are rather passive.
However, we cannot disable the default email notifications and now my agents are getting spammed.
There is already a ticket view that filters the tickets where one has been added as a Watchr - they can go there and check the status of a ticket, if needed. 
I think we need to be in control of the email notifications that are sent from Freshdesk to the customer and also to our internal team.
