Optimistic Ethereum Tx not imported Metamask

Describe the problem:
I have transactions done in Metamask Optimistic Ethereum. However when I do the import transactions for Metamask, only the Ethereum Mainnet transactions come through. The Optimistic Ethereum L2 ones don’t show up in Transactions. How do I get those in?

Which exchange/wallet is this regarding?
Metamask

How did you import data into this wallet?
Auto sync

What have you tried to fix this so far?
I don’t know how to pull this information.

FYI I fixed the issue myself by creating a CSV import, after downloading history from Optimistic Ethereum.

Where can I download the CSV?
