Unable to connect to Pancake using Eth mainnet

Just starting to delve into the world of DEX.

So, I setup my Metamask to accept incoming transfers from Binance BSC. Transferred BNB to MetaMask using BSC with no troubles.
But when I try to select the Eth Mainnet to connect Pancake to my MetaMask wallet, I get an “Unsupported chain id” error.


I tried to connect Pancake to me MetaMask using the BSC net and THEN revert MetaMask to the Eth Mainnet, but it just disconnects.

I am guessing I’m just missing something, but anyone with thoughts on how to make this work.


As i know, Pancake is only for BSC, not for Eth mainnet
