!withdraw: Same problem as not adding the [chain] argument.

After displaying the balances in the "UTXO and NEVM" chains, the !withdraw command takes no arguments, and therefore can only be withdrawn by the default "UTXO" chain.

• One option would be to add the need to apply a [chain] argument for the user to decide which wallet in the chain they want to withdraw funds from.

• The ideal solution would be that the [address] argument could be parsed;

If the argument starts with 0x {
the bot executes the transaction on the NEVM chain;
} else if it starts with sys1 {
it executes the transaction on the UTXO chain;
} in case none of the cases are met {
return an error message that the address is wrong;
}
