Can't seem to do anything wallet asset on Polygon network

I have a small USD Coin (PoS) balance in my Coinbase wallet. I have tried to bridge it to the Ethereum network and I keep getting the following error message:You have $0.00 in MATIC, but you need $0.03 due to gas feesHow do I get this done? How do I get MATIC? Just buy it on the exchange? via /r/CoinBase https://ift.tt/UAQ7uvC
