Can not moveatic from Ethereum mainnet to polygon/matic mainnet in metamask

I have the Polygon/matic mainnet connected to my wallet. I sent some matic to my wallet from Coinbase, but it will only show up on the Ethereum mainnet. How can transfer it to the polygon/matic mainnet so I can play aavegotchi?

Hi, sorry for the inconvenience, do you use Metamask app or the chrome extension?

I use the app on my phone.
