It's possible there may have been some confusion here between "SEZ" and "says"

One factor affecting benefits available on this itinerary may be if the aircraft is operated by Indigo. Here are some experiences reported by others in that scenario:

Codeshare with Indigo - Oneworld Emerald

Qatar flight number on an Indigo operated service

So it seems it would be no lounge in that case. But it would also be unusual if there is nothing offered if the flight is both marketed and operated by QR. We shall probably have to wait to hear from a poster with direct recent experience of that.
