DogeChain Private Key Transfer Options

Hello folks, late to the party but was notified that DogeChain has shut down. I have my information, but wondering what my options are for where I can move my wallet?

The first few places I've looked are only able to transfer wallets using seed phrases. Any ideas are welcome.

I'm also pretty green to crypto so sorry if I'm not understanding something or phrased something incorrectly. Thanks!
