Number of clicks needed to install flashplayer update

I have a macbook pro running macOS Sierra (10.12.6) and received a notification to update my flashplayer.

It takes me about 5 clicks to download and install flashplayer update. Steps are like 'download', 'click on install' , 'allow install', 'install', 'finish' ... who needs a 'finish' step at the end? is it not obvious??This looks like an experience I'd expect 15 yrs ago - so out of place with the rest of time I spend on my mac.

Is it so difficult for you to fix this  technically? or is customer experience so low in priority for you that it has never occurred to spend some time in improving this?
