container repository sync mirror option missing

[vkukk]

Summary

I'm trying to start using Pulp 3 as container registry, following official tutorial https://pulpproject.org/pulp_container/docs/user/tutorials/sync-and-host/#sync-content

The tutorial mentions mirror=False|True option and claims:

In the above example, the payload contains the field mirror=False. This means that the sync will be run in the additive mode only. Set mirror to True and Pulp will pull in new content and remove content which was also removed from upstream. The same logic will be applied when include/exclude_tags are specified together with the mirror command, but only on the subset of tags.

I don't find anything in pulp-cli documentation about this mirror option nor does pulp-cli --help provide anything related.

What is the "payload" in this context at all? How do I make sure that mirror=False? Which object should have this parameter?

Also, when following instructions, the sync does not work:
