How can i simplify multiple conditions?

public LocaleSymbol HandleFormatting(string formattingCode, LocaleSymbol prevSymbol)
{
    if (formattingCode == "#")
        prevSymbol.Wrap = true;
    else if (formattingCode[0] == '%')

    else if (formattingCode.Contains('~'))
    {
        var perLetter = formattingCode.Contains('@');
        var parsedShakingData = formattingCode[(1 + perLetter.ToInt())..].Split(", ");
        var shaking = new Shaking((Vector2.One * int.Parse(parsedShakingData[0])).ToVector3());

        shaking.IsLerped = bool.Parse(parsedShakingData[1]);

        prevSymbol.Shaking = shaking;
        prevSymbol.ShakingWholeFragment = !perLetter;
    }
    else if (formattingCode[0] == '&')
    {

    }
