Indigo Airlines — Lost Gold Chain in Flight 6E - 5338

I Farha Khan was travelling from Agra to Mumbai yesterday on 30.01.24. I was travelling via Indigo Airlines (6E-5338) PNR number - P2E55K. I seem to have misplaced/dropped/lost a gold chain earlier yesterday during my transit. I would be highly obliged if contacted, if any such item is found as the chain is very valuable to me both personally and financially. I was wearing the chain when I boarded but I noticed it missing after arrival...
