Documentation says to create a "Classic Slack App" but these are discontinued

Hi,
Both the README and the documentation tell users to create a "Classic Slack App" but on the Slack side, these are discontinued and can't be created:

Can the documentation be updated to recognise this and provide users with up to date info?
Either "modern" Slack Apps can be used, and users should be told how to do so, or they can't, in which case users can't start using the bot today and only pre-existing installs will work (i think), and users should be told so.

Thanks!

Hey, that it correct. Currently the best (and only) option for new installations is to use the webhook bridging.

#787 is a work-in-progress conversion into a modern Slack app that'll hopefully, eventually obsolete both other methods.

We would like to be use this bridge as well but as mentioned above, you can no longer create a Classic Slack App.
