How to sell/swap Palm.io DAI?

I've bought 50 DAI on the palm.io network for the Nifty's Matrix NFT campaign, but I was not able to use them, because the buying queue was too high and all the NFTs were sold out.

Now I have 50 DAI on the palm.io network, that I can't use. How can I sell them or swap them to BSC or AVAX? I know that you can use the https://app.palm.io/bridge to transfer to Ethereum, but due to the very high gas fee and bridge fee, it does not make sense to use it.

Any idea or suggestion?
