REST API Equivalent for "tmsh show cm device-group Sync-Failover"

Hi! I found the REST API for the TMSH command mentioned in the subject line:

/mgmt/tm/cm/device-group/~Common~Sync-Failover?expandSubcollections=true

But I can't find the following values that comes with the CLI:

Time Since Last Sync (HH:MM:SS)
CID Originator
CID Time (UTC)
LSS Originator
LSS Time (UTC)

Please advise Thanks

J.
