GitHub Slack App Authentication Fails – No Way to Regenerate Expired Link

[emluth]

Describe the bug
After installing the GitHub app in Slack, the authentication link provided expires after a certain period. Even after uninstalling and reinstalling the app, the authentication process remains broken—there is no way to generate a new authentication link, preventing users from connecting their GitHub accounts.

To Reproduce
Steps to reproduce the behavior:

1. Install the GitHub app in Slack.
2. Click "Connect GitHub account" and proceed with authentication.
3. Wait until the authentication session expires.
4. Attempt to reconnect from Slack—there is no option to generate a new authentication link.
5. Uninstall and reinstall the GitHub app in Slack.
6. Try again—authentication still does not work.

Expected behavior
Users should be able to generate a new authentication link from Slack after the original one expires. Reinstalling the app should reset the authentication process, allowing users to connect their accounts.

Screenshots

Desktop (please complete the following information):

• OS: Apple M3

Additional context

• There is no way to manually request a new authentication link from Slack.
• Reinstalling the app does not clear authentication issues.
• A command or button within Slack to generate a new authentication link would resolve this issue.

@emluth you can run the undocumented command /github signin.
