Automate a “click” whenever it pops up using iMacros or similar software?

I'm trying to automate removing Instagram followers from my account. However, I don't want to remove everyone nor do I want to remove x amount of followers at random. My goal is to automate the second "Remove" button that pops up when I click the first "Remove" button. For example:

1. I manually click Remove
2. Automatically have iMacros click the second Remove button

This way I can choose who I want to remove as a follower without having to click the 2nd follow button.

I have over 5,000 followers I want to remove so this automation will speed things up. I included a screenshot below:
