Can't use `tapBip32Derivation` to sign PSBT

[archidoge0]

I noticed the field is included:

tapBip32Derivation:     [0x16, Bytes32,             TaprootBIP32Der,  [],  [0, 2], false],

but in transaction.ts, only bip32Derivation is desired:

if (!input.bip32Derivation || !input.bip32Derivation.length)
  throw new Error('bip32Derivation: empty');

Could you share an example to sign input as taproot key spend path using tapBip32Derivation?
