> We are focused on making Slack accessible to all people. Over the past year, we've made great progress in improving both the keyboard and screen reading experiences in Slack.

Here's a thought: how about you write a native app for each platform? I can guarantee that the hundreds, if not thousands, of engineers working on AppKit and Windows APIs are a lot better at getting this to work than your team.
