Hyundai is "terminating their deposit program for the GDRs" - ELI5 please?

What I gather is that they are basically no longer supporting investing through foreign markets, but they go further to say that they will convert GDR shares to ordinary shares but that "South Korea is a market that requires disclosure of beneficial ownership... Each investor needs to be registered with a unique local market ID..." and so on. Does this mean that as a typical US investor I can no longer invest in Hyundai?

TIA!
