I've a contract which emits event with string array as follows:

event OnTransfer(
    address indexed to,
    address indexed from,
    string[] indexed indexedTransferIds,
    string[] transferIds,
    uint256 amount
);

function transfer(
    address to,
    uint256 amount,
    string[] memory transferId
) external {
    bool transfered = token.transfer(to, amount);

    require(transfered, "Transfer failed");

    emit OnTransfer(to, address(this), transferId, transferId, amount);
}

I want to filter logs with the indexedTransferIds topic. According to the documentation here the event parameter is hashed as below:

the encoding of an array (both dynamically- and statically-sized) is the concatenation of the encoding of its elements, always padded to a multiple of 32 bytes (even bytes and string) and without any length prefix

What's the way to create the data so i can use it as topic in my log queries?
