OME 3.1 Redfish command to delete an asset from OME

Hello,

We are in the last version of OME.

I'm able to list or declare an asset inside OME (in redfish command) without issue.

But i'm still searching how to delete one.

Considering i have one asset (hostname "azerty") which is available in "All Devices" group in OME.
With a request to list all the assets in this group (id=500), i find my asset as his "internal_id" to 75489.

Reading the documentation, the method i thing doing my goal is : /GroupService/RemoveMemberDevices

I make a POST with the good body/payload {GroupId = 500, MemberDeviceIds: [75489]}

The API return me a good answer (a 20x, i dont remember exactly).

But the asset never disapear from the appliance.

Can you help me on this please ?

Which is the good way/method to delete an asset from OME.

Thanks !
