Making Ethereum transaction smart contarct input data in human readable

In the following tx on testnet I'm looking to understand what the bytes value being passed as an input parameter actually is in a human readable form:

Tx: https://goerli.etherscan.io/tx/0x05da01fee2338a71956d8209b53364b1e9b9eaab3bf29e58f089438d7b06d7d1

Input data decoded using etherscan: 0

_palette

bytes
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

How can I convert this bytes value into a string or something human readable?

I've tried base64 decoders and i've had no luck.

To make a transaction human readable you need

  • To have the ABI files of the compiled smart contract to know what is the function call in the transaction

  • To have the source code of the smart contract and read it what it does when this function is called

Then you can match the data field to the Solidity function selector and the function arguments.
