switch from one network to another tokens

Hi, I need help!! I have put from Binance to Metamask ETH. This all perfect. The problem is that when trying to put gasoline in OpenSea, it is not possible with any other network than the default Metamask, and my EThs are in another network that I had to manually do Smart Chain to receive from Binance. How do I go from one network to another in the same metamask?
