How to click a Safari toolbar Extension button using AppleScript (when in full screen)

Question

I'm trying to write a small AppleScript which will click the OneNote toolbar Extension, so I can bind it to a keyboard shortcut. The script below works perfectly as long as the instance of Safari is in windowed mode, but in full screen it fails and returns the error:

error "System Events got an error: Can’t get window 1 of process \"Safari\". Invalid index." number -1719 from window 1 of process "Safari"

I have exported this script as an application and granted accessibility access to it. Effectively it seems as though a full screen Safari window is not given an index or is no longer a window and is now a different object.

tell application "System Events"
 tell process "Safari"
    click button whose description contains "OneNote" of toolbar 1 of window 1
 end tell 
end tell

try this script. It works whether Safari is in full screen mode or not:

set myButton to "OneNote"

tell application "System Events"
    tell process "Safari"
        set isfullscreen to value of attribute "AXFullScreen" of window 1
        if isfullscreen is true then
            click ((buttons of toolbar 1 of group 1 of window 1) whose description contains myButton)
        else
            click ((buttons of toolbar 1 of window 1) whose description contains myButton)
        end if
    end tell
end tell

Replace "OneNote" with any button you'd like to click.
