Ribbon customisation - how to find XML

[DonAndress]

Hello.

I received a file where a developer used Ribbon customisation.
I can see the additional menu, additional buttons and now I'd like to modify that.
The problem is I can't find any XML.
There is no code in VBA, there is no XML map, can't see any standalone XML, option "Preview Data in Task Pane" in XML Source pane is inactive.

Can somebody please help me understand where else I could look for it?
I use Office 365.

It used to be that the xlsx file is in fact a zip file in disguise in previous versions of excel whether it is the same now I do not know
I used to open an xlsx file with a zip file utility and you will see a number of files one of which is the xml file, once extracted you can edit in notepad and replace it in the zip/xlsx file

Also, you can use the following editor to customize the ribbon...
