"Revert to previous settings" to plugin device

Hi,

I’m looking for some help to use the “Revert to previous settings” on Scene (the little red arrow) with my virtual device.
It works well with real device but not with my plugin.

On log there is,

with real device :

XXX-CreateRestorePoint device 121 service urn:upnp-org:serviceId:Dimming1 restore (null)
XXX-CreateRestorePoint device 121 service urn:upnp-org:serviceId:Dimming1 restore 0 onoff 0x9bfa70 dim 0x9bfb18
...
XXX-GotoRestorePoint device 121 service urn:upnp-org:serviceId:Dimming1 restore 0
...
XXX-ResetRestorePoint device 121 service urn:upnp-org:serviceId:Dimming1 restore 0

with virtual device :

XXX-CreateRestorePoint device 115 service urn:antor-fr:serviceId:PilotWire1 restore (null)
XXX-CreateRestorePoint device 115 service urn:antor-fr:serviceId:PilotWire1 restore (null) false
...
XXX-GotoRestorePoint device 115 service urn:antor-fr:serviceId:PilotWire1 restore (null)

So, i think issue is on “CreateRestorePoint” but i have no idea what function is calling, and how to implement them.
