@telukir_gitlab Make sure you see Gitter Private Repo Access and Gitter Public Repo Access on https://github.com/settings/applications. Do you see both?
Once you see them personally, also make sure you see them on
The docs you linked are what you are after: https://gitlab.com/gitlab-org/gitter/webapp/blob/develop/docs/faq.md#why-isnt-my-github-organisation-or-repos-appearing
@behrangsa These issue for gitlab-org/gitter/webapp#365. The idea is that you'd be able to see what messages you reacted to and so you don't need gitlab-org/gitter/webapp#2420. Improved UI/UX for creating threads is part of our planned redesign.
The redesign is happening in the next couple of months, implementing reactions is not scheduled.
