Can you swap Optimism to ETH?

Excuse me, I was wondering if you could assist me with a question regarding cryptocurrency. Specifically, I'm curious if it's possible to swap Optimism tokens for Ethereum (ETH). I'm new to the world of crypto and I'm trying to understand the various ways to trade and exchange different digital assets. If it is indeed possible, could you provide some guidance on the process, perhaps highlighting any potential challenges or considerations I should be aware of? Thank you for your time and assistance.
