Confirm button before spending gold

This is particularly for mobile usage, I have accidentally pressed the use gold button many many times on things which is not only annoying but literally costs money. Pressing gold during research is particularly frustrating as it is expensive. I’ve done this many times instead of pressing the exit button and I believe it shouldn’t be so easy to accidentally hit it.

I would like to see a ‘confirm’ button prior to spending any gold. Thoughts?
