Batching email notifications is disabled in Data Center 10.3 and I can find how to re-enable it

[Alastair Munro]

Docs advise you can find it under Mail, but there is no option. Also displaying System Info it shows:

Jira inform - batchers - 4.1.5 Disabled

Jira inform - batching plugin - 4.1.5 Disabled

Reason I want to enable it is Jira Troubleshoot and Support plugin fails to enable as the batching plugin is not available:

Can't find it I mean.
