How to get the coin address from the extended public key/ public key
I tested on some coins below it worked but Bitcoin and Ethereum.

CoinType.DOGECOIN,
      CoinType.DASH,
      CoinType.POLKADOT,
      CoinType.SOLANA,
      CoinType.NEAR,
      CoinType.XRP,

I want to save the private key securely. I only use the private key with the user grant. so I want to use the public key to generate other coin addresses.
