Finding files with same name but different extensions across drives

I am trying to find multiple files across folders or drives which have similar name but different extension

abc.docx abc.pdf
def.epub def.pdf or
ghi.jpg vs ghi.png.

I found some threads of using some button or code if all these files are in same folder and if they are all selected first.

As many of these files with same name and different extensions have been organized across different drives and folders, I am not sure where all they exist. For this reason, I will like to use Find tool if possible. If not possible to do it through Find tool some button or script which helps with this will be welcome.

Please note that I am not yet very fluent with customizing scripts other than minor changes in it and dragging and dropping them somewhere as directed step wise.

The Fetch command is the closest thing to that:
