Swapping ETH or USDT to BUSD

Hi there

It looks like ETH and USDT can be swapped to BUSD.

I have already set up/configured Smart Chain Network in Metamask.

Question: Will the newly swapped BUSD automatically end up on the Smart Chain Network part of Metamask or will them be sitting on the Ethereum main net? If the latter, how to get it shifted to the Smart Chain part of Metamask?

Thanks for clarifying!
