Getting group's "active" status using dBus

[exquo]

In the output of signal-cli listGroups there is an Active: true field for each group. But it is absent from the output of the dBus version of the listGroups command.
How can this status be obtained from a dbus method?

The man page lists a number of properties that can be obtained through a group interface, including

IsMember (read-only) : always true (object path exists only for group members)

But there does not seem to be a counterpart to the plain-output's "active" property.

Also, what exactly does an "active" status signify? Is a "non-active" group a group that I am no longer a member of? If so, should such group be even included in the groups' listing?

Active: true means the user is a member of the group (the name comes from the group sync message which has an active field)
So the IsMember dbus property corresponds to the active flag.
The listGroups command outputs all groups. When the user leaves a group the group information doesn't get deleted automatically, which matches the Signal-Android behavior.

Thanks, that clarifies it!
