Moved to Drupal 11, Need Slack Notification Module

Problem/Motivation

Looking for Drupal 11 Slack notification module

Steps to reproduce

I'm moving my Drupal 8.5 site to Drupal 11.2.2. I haven't been able to find a compatible module for sending a notification to Slack whenever new content is created.

Proposed resolution

I'm currently using a convoluted solution that requires a bunch of dependent modules whereas with 8.5, only a single module was needed to perform the simple task of sending a notification to Slack upon specified events.

Remaining tasks

Please continue maintenance on this module to produce a version that is compatible with Drupal 11.

User interface changes

API changes

Data model changes
