Slack Integration Not Working – Truncates Setup

I’m evaluating this product for purchase of the pro suite. When I try to use the Slack Integration, when attempting to add to the field Webhook URL, it truncates the URL “Https:” and just allows “//hooks.slack.com/services/…”. I’m attempting to change this field in the “WP Live Chat Support Settings” -> “Slack Notifications” -> “Slack WebHook”. I tested with this truncated URL, and doesn’t put anything in the Slack channel

I am using Chrome.
