Screen mirroring not working from my oneplus one with lineage os becon 16

Device: OnePlus one| Os: lineage os becon 16| Issue: screen mirroring

I am not able to cast my phone to TV , as there is no option to enable wireless display, hence TV is not getting listed in cast option.

But am able to see TV is getting listed under WiFi direct and am able to connect to it. But no casting/mirroring happening with it.
