Can I swap Polygon on Uniswap?

I'm curious about the possibilities of swapping Polygon on Uniswap. Is it possible to directly trade Polygon tokens on this decentralized exchange platform? If so, what are the steps I need to follow to initiate the swap? Additionally, are there any fees or limitations associated with this process? And what other cryptocurrencies or tokens can I potentially swap Polygon for on Uniswap? It would be great to get a clear understanding of the process before I dive in.
