Issues

The RTM client used to receive messages cannot search and may not be able to send all of the messages supported by the bot. Look at using the web client as well.

The web client requires a user token vs the RTM client's bot token, along with the channel.history scope (in addition to existing chat.write.bot and bot scopes). Config and slack app have been updated accordingly.
