Feature Description

I'm trying to figure out the L1 tx (ie tx on Ethereum mainnet) that corresponds to my L2 tx (ie tx on Optimism). I understand txs are posted in batches, and so I need to find the batch that included the l2 tx hash. I'm thinking of doing this by correlating the time range my tx was submitted (not sure if there's a better way).

The part I'm stuck at now is how to decode the tx data from the raw blob data. How can I go about decoding the blob data? I don't see any tools either I can use
