How to add native address for some uncommon tokens to MetaMask wallet?

[zydjohnHotmail]

Hello:
I want to bridge some BTCBAM tokens from its native network ‘BTCBAM’ to Ethereum (ERC20) network, so I can get some wrapped BTCBAM tokens.
I know its contract address on BSC is: 0x79abC799ae4B749C01e07a60c8687A49D128eA1C
But my MetaMask wallet address is EVM address like: 0x…., I can find one BTCBAM native address is something like this: Bq4Ei1WxgnN6VD5jxeTtMSdvLfK8as7sJM
In order to bridge BTCBAM from its native address to ERC20 address, I think I need some BTCBAM address in my MetaMask wallet, right? But how can I get one of such address.
I found some articles from BTCBAM web site talking about BTCBAM wallet, I think those address in BTCBAM wallet should be the native network address.
I want to know if I can use BTCBAM wallet to generate a deposit address, and export the address using the wallet private key, then use MetaMask wallet to import the native BTCBAM address with its wallet private key. If it works, then I can add native BTCBAM wallet address in my MetaMask wallet, then later on go to some bridge web site, to bridge the BTCBAM tokens from its native network to ERC20 network, I want to get the wrapped BTCBAM tokens on ERC20 network.
Please advise if I think in the correct way or not.
Thanks,
