Posting from Slack to Bubble

Hey, I have an app where I want users to be able to post from their slack group and the data is pushed back in the Bubble app.
This needs to work for anyone’s slack environment (not just mine), so they’d need to authenticate their particular slack instance, and then when they post to a particular slack channel (let’s say it’s called ‘feedback’) this is pushed back to the Bubble app.
Any ideas how this could be achieved?

A while back I did a study to do something like this. Slack has changed their APIs quite a bit since, but it was achievable. What I had to build was a Slack app that would listen to something and – when triggered – it would execute a series of steps, one of them to send an API call to my Bubble app.

Back then I didn’t have to deal with the complexity of multiple Slack environments, though.
