Nvsci Streams Late Attach and Reattach

I am hoping to get late attach and reattach working for Nvsci Streams ( Late-attach/Re-attach Consumer | NVIDIA Docs ).

I have tried modifying the sample app in many ways to get late attach working, yet I am still dealing with issues. Do you have a minimal working code example or psuedocode for allowing consumer and producer to proceed before all attach? And code for allowing reattach.

Dear @bala.vinaithirthan ,
In DRIVE OS 6.0.10, nvscistream event sample (/drive/drive-linux/samples/nvsci/nvscistream/event)demonstrate the usage of late attach/reattach consumers. Could you please check it?
