How to skip the popup message boxes?

Question

I am trying to open and save excel files to prevent the corrupt-load using .NET Framework (4.8). However, the file I am trying to re-save has some pictures in it and is an .xlsm file. How can I skip the popup messages? I tried to Sendkeys but it seems to not work. My code is attached below for review. Any suggestions?

using System;
using System.Windows.Forms;
using Excel = Microsoft.Office.Interop.Excel;

namespace ReadingExcelData
{
class Program
{

    static void Main(string[] args)
    {
        try
        {
            Excel.Application xlApp = new Excel.Application();
            xlApp.DisplayAlerts = false;
            xlApp.Visible = false;
            xlApp.UserControl = false;
            xlApp.AskToUpdateLinks = false;
            string my_path = "link to input xlsm file";
            string output_path = "link to output xlsm file";
            Excel.Workbook book = xlApp.Workbooks.Open(my_path, 0, Type.Missing,
               Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Excel.XlCorruptLoad.xlRepairFile);
            if (book.HasVBProject)
            {
                book.SaveAs(output_path, Excel.XlFileFormat.xlOpenXMLWorkbookMacroEnabled, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
                SendKeys.SendWait("{right}");
                SendKeys.SendWait("{right}");
                SendKeys.SendWait("{right}");
            }
            else
            {
                book.SaveAs(output_path, Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
            }
            book.Close(true, Type.Missing, Type.Missing);
            xlApp.Quit();
        }
        catch(Exception)
        {
            System.Windows.MessageBox.Show("Caught error");
        }

    }
}

}
