How to display the code of a command?

Good night. I have a file with an .xlsm extension which has some commands enabled in the ribbon (see image). I would like to see the code for these commands to make some modifications but when I press F11 I cannot find the associated macros. It seems that someone had deleted them. Is there a way to find the VBA code for these commands? Thank you very much in advance.q1.jpg

If you do not find a procedure declaration similar to the one below in the code, it may mean that there is a built-in Excel functionality behind the icons. Only the icons for these buttons have been changed.

Fragments that may have a different name are marked in red. In blue - a fragment that must appear unchanged.
To be sure, you can edit the workbook (actually its ribbon) in Custom UI Editor for Microsoft Office.
