check whether getlastmatch or location is in region

I want to check whether getLastmatch is in the region.
If matched image is in region, do not click.
If matched image not is in region, click.

dont click = Region(x,y,w,h)
if exists("123.png") then

match = getLastMatch()
x = match:getX()
y = match:getY()
click(Location(x-200,y))

if not dont click:getLastMatch() then

toast("It's safe to click")
else

toast("NOOOOOOOO dont touch")
end

end

like this. but i dont know how to write the condition.
