Sample taproot spending transaction on signet

[vjudeu]

Is there any example? I tried doing it myself with private key equal to one, but so far Bitcoin Core does not know how to sign that transaction:

Code:

signrawtransactionwithwallet "02000000015248ca4550bf88baa3b8d2e763c2bc169526e5f140ce3fe01ad2a7fac7524b330100000000ffffffff01905f010000000000160014751e76e8199196d454941c45d1b3a323f1433bd600000000" "[{\"txid\":\"334b52c7faa7d21ae03fce40f1e5269516bcc263e7d2b8a3ba88bf5045ca4852\",\"vout\":1,\"scriptPubKey\":\"512079be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798\",\"witnessScript\":\"79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798\"}]"
{
  "hex": "02000000015248ca4550bf88baa3b8d2e763c2bc169526e5f140ce3fe01ad2a7fac7524b330100000000ffffffff01905f010000000000160014751e76e8199196d454941c45d1b3a323f1433bd600000000",

    }
  ]
}
