Group options in the REST API

Hi guys,

Does anyone know if/where the following group settings are in the REST API?

1, “Enable delayed project deletion”, and its “Enforce for all subgroups” options.

2, “Prevent forking outside of the group”

3, “Allow subgroups to set up their own two-factor authentication rules”

4, “Prevent adding new members to projects within this group”

Thanks,
Andy.
