Automating Zoom.us app with applescript

I'm helping disabled person to adapt Zoom application for their special needs. The problem is that zoom exposes only raise hand reaction via Option + y keyboard shortcut. My goal is to let this person express other reactions like yes, no and ... using keyboard shortcuts connected to special equipment. I find it challenging to access the reactions menu via Applescript. Additionally, zoom shows menu with reactions button only when user hover mouse. I started my script as

tell application "zoom.us"
	activate
end tell
try
	tell application "System Events"
		tell process "zoom.us"
			tell window "Zoom Meeting"

-- some magic that reveals menu with buttons and press reactions button goes here

			end tell
		end tell
	end tell
on error errMsg
	display dialog "Error: " & errMsg
end try

Thanks for your help!
