Description

I was excited to have an official Slack MCP that didn't require a bot token. The first thing I tried to do was update a message in a channel, but it's not possible. Could you consider adding message editing support please?

My use case is a weekly list of seat allocations I post for hot desking that I have to update as people say they won't be in attendance or are sick or on holiday etc. It would have been nice to automate this!

I don't want to use a Canvas for this, it's not visible enough.
