Click Chrome Alerts

I am trying to create a web scraper to automate things that administrators do on a website. Although it would be better to have a script run this, I decided a web scraper would be a very fast and simple solution. I would like an admin to be able to use the web scraper to click buttons that reset and clean parts of our data. However, the final click only works if the user is able to click an alert the appears in Chrome. In googling and searching through documentation and the forum, I did not find a way to click an alert button. Even just a keyboard input enter would work, and would allow desired actions to follow.
This would ideally be another selector after the final link click.

I understood selenium and other more intense web scraping tools can do this, I just wanted to use this tool since it had a fast getup and go.

Url: https://admin.relativefinder.org
Note: you will not be able to access the site as it has admin permissions with highly restricted access.
Sitemap:
{"_id":"admin-do","startUrl":["https://admin.relativefinder.org/#/groups/featured"],"selectors":[{"id":"group","type":"SelectorLink","parentSelectors":["_root"],"selector":"td:nth-of-type(2) a","multiple":true,"delay":0},{"id":"click-purge","type":"SelectorLink","parentSelectors":["group"],"selector":"a[ng-click='purger()']","multiple":false,"delay":0}]}

The WS sitemaps only interact with websites, not Chrome itself, so it doesn't seem to be the solution for this. Selenium is actually more of a automation/testing tool so would indeed be suited for your task. You can also look at Helium, a kind of add-on for Selenium which makes it even easier.
