Access and click the 'paperclip' icon

I have 3 UI elements in splitter group 1 of splitter group 1 of window ‘LINE’:

  • text area 1
  • list 1
  • grow area 1

Using UI browse, I can:

  • highlight the entire splitter group 1 of splitter group 1
  • highlight text area 1 of splitter group 1 of splitter group 1
  • highlight list 1 of splitter group 1 of splitter group 1

I can use AppleScript to access text area 1 and list 1. However, I cannot use UI browse to display 3 clickable icons , and cannot use AppleScript to access 3 clickable icons below “text area 1”.

Manually clicking the ‘paperclip’ icon will launch Mac’s Finder.

This is what I want to achieve with AppleScript: access and click the ‘paperclip’ icon. Please help me!"
