Tunnel identification from cEdge Netflow

[JB71649]

Hi,
  We are trying to figure out how to map cEdge flow export with the tunnel the flow is taking. Is there a way to do it?
We observe the netflow from cEdge has some special fields,
12342 - ingressoverlaysessionid
12433 - egressoverlaysessionid
12441 - connection id long

could these fields help identify the tunnel? If so how could we map the ids to tunnels?

Thanks

We want to map the session IDs coming from NetFlow to tunnel sessions. Any REST API/ CLI command that provides tunnel sessions with session IDs?
