I want to improve the this code by adding if or switch case:

Original code:

           {(errorMessage || invalidEmailError.length > 0) && (
            <Message type="error" className="mt-l">
              {`If an account exists` || invalidEmailError}
            </Message>
          )}

I want to change Message type="error" to Message type="success" so I tried this:

      {invalidEmailError.length > 0 && (
        <Message type="error" className="mt-l">
          {invalidEmailError}
        </Message>
      )}
      {errorMessage && (
        <Message type="success" className="mt-l">
          {`If an account exists `}
        </Message>
      )}

If it possible to use if or switch case here so I can improve the code?
