thanks, do you know here: https://iancoleman.io/bip39/ which field contains the root keys? I tried both: `Account Extended Public Key` and `BIP32 Extended Public Key` to pass to `addressesFromExtPubKey`, but again m84 was returned, strange

Where in your code are you trying to pass the derivation path as m/44'/0'/0'/0? I don't see it in your question. Also, xpubs already have the derivation path encoded in them. You can't change an xpub's deriv without changing the root and then create a new xpub/ypub/zpub.

# How to derive BTC m44 addresses from xpub?

(Asked by: username_0 on 2021-02-26)

I checked Swan's Address Derivation Library https://github.com/swan-bitcoin/xpub-tool.
I try to get m44 address, but I got m84. Why? Do you know is it any parameter to force return m44? I tried to pass path: "m/44'/0'/0'/0", but it did not help.
Do you have any idea?

  );

export const addressFromXPub = (key) => {
  console.log(
    addressesFromExtPubKey({
      extPubKey: key,
      network: "mainnet",
      addressCount: 3,
    })
  );
};

[
    {path: "m/84'/0'/0'/0/0", address: "bc1qfgnqm6g46ys0h9gh606m76wemka2rrttrac90x"

The following key:
xpub6C5oXscLYZwgq2DB42TFC32QcoPa1MeCWUNPZSjydunniCM77TRcBfFnjScJeToVXS5RBDr53Ls5RXvDHujmFSL4Fqc9kkpsMjU1vg68xv7

Corresponds to a level 3 public key w/index of 0x00000080 which is 0h/0'. In the context you've described it probably corresponds to "m/?/?/0'". This key's parent's fingerprint is 0x3ab9169c, so you'd need to provide the parent's full fingerprint to confirm the original derivation path.
Although m44 & m84 have the same master/root key, they have completely different level 1 keys, which would change all lower nodes. In short you can only derive m/... full paths from root keys, not child keys, which you've provided.
Edit: The key you've provided is probably meant for deriving receive & change addresses of a certain address type.
