Can I move my BNB tockens from my etherium account to my Smart chain account on MetaMask?

I have BNB on Ethereum Mainnet, when i connect to Pancakeswap it says wrong netwrork

When on BSC smartchain it connects but says insufficient balance, since BNB on Mainnet is not recognised on Smart Chain.

Any thoughts, solutions etc., would be appreciated.
