Thunderbolt gigabit ethernet port

I am based in India. For my 2019 MacBook Pro, I bought a thunderbolt Gigabit Ethernet adaptor, by mistake given MacBook Pro has only USB-C ports. Apple India does not have a return policy.
Can someone guide if there is a thunderbolt to USB-C adaptor. Having searched in, there are adaptor, but dont ship to India.
Any guidance would be greatly appreciated

I believe this is a link to one on the Apple India site. Hopefully this works out for you

If it’s not opened, then the should be able to swap it. But I can understand the regional restrictions. Try calling Apple support and see if they can help you.
