Tested on my end and can go through the whole process successfully. Thanks for your hard work!
The only concern I have here is that when a user clicks "remove" after the slack app was installed in the designated workspace, the settings panel shows it is removed, but actually it was not. The removal only means disconnecting the slack app from our system, and the slack app will still be there. Users will need to go to the slack app management to uninstall it. This is kind of confusing. However, I know that it's hard to help users uninstall from our platform, but maybe some tweets of the wording would make the user experience better imo.
