Is it possible to use rainbowkit with flashbots?

[cattingcat]

I tried to use it to send flash-transaction and got tons of problems

• It is quite difficult to detect if it is metamask (metamask doesn't support signing transaction without sending it)
• signTransaction function just returns unsupported_operation but for example WalletConnect support it https://docs.walletconnect.com/json-rpc-api-methods/ethereum#eth_signtransaction
