Another suggestion re emoji: using Message Shortcuts for greater visibility/discoverability? https://api.slack.com/interactivity/shortcuts Might need to combine this with Slack modals for information gathering (if it lets you do this). - Source: Hacker News / over 1 year ago

Outside of the Block Kit UI, Slack has support for two other interactivity systems: Slash Commands and shortcuts. Slash Commands are entered by a user in Slack’s text input (available in every channel), while shortcuts are graphical in nature. Since they’re easier to visualize, we’ll demonstrate shortcuts by creating a shortcut that will fetch our list of contacts and give us the ability to edit them. - Source: dev.to / about 2 years ago

You can do the notified "on every message part," and could have it intercept the message and replace/append the message with content, but you won't be able to add a text editor button. You can, however, add actions to the lightning bolt and message actions sections, as described here: https://api.slack.com/interactivity/shortcuts. Source: about 3 years ago
