How to use the @liquality/bitcoin-utils.compressPubKey function in @liquality/bitcoin-utils

async getLedgerAddresses (startingIndex, numAddresses, change = false) {
    const walletPubKey = await this.getWalletPublicKey(this._baseDerivationPath)
    const compressedPubKey = compressPubKey(walletPubKey.publicKey)
    const node = bip32.fromPublicKey(
      Buffer.from(compressedPubKey, 'hex'),
      Buffer.from(walletPubKey.chainCode, 'hex'),
      this._network
    )

    const addresses = []
    const lastIndex = startingIndex + numAddresses
    const changeVal = change ? '1' : '0'

    for (let currentIndex = startingIndex; currentIndex < lastIndex; currentIndex++) {
      const subPath = changeVal + '/' + currentIndex
      const publicKey = node.derivePath(subPath).publicKey
      const address = pubKeyToAddress(publicKey, this._network.name, 'pubKeyHash')
      const path = this._baseDerivationPath + subPath
