Ask the guy who wrote it: GitHub - JanKallman/EPPlus: Create advanced Excel spreadsheets using .NET[^] - there is an "Issues" forum, so if the documentation isn't clear, that's the place to start...

Initialize excelPackage without any parameters, then it uses its own internal stream, which is later filled by package.Load(array)

public static ExcelPackage ConverByteArrayTOExcepPackage(byte[] byteArray)
{
    using (MemoryStream memStream = new MemoryStream(byteArray))
    {
        ExcelPackage package = new ExcelPackage();
        package.Load(memStream);
        return package;
    }
}
