+1 from me for auto-connect camera, audio-record and personal-files to slack since all are clearly required for the snap to properly operate. In the case of personal-files, the requested directory is clearly owned by the slack snap so it makes sense.
There is no need to request auto-connection to audio-playback since it is auto-connected by default.
Also, I don’t see yet the strictly confined snap uploaded to the store. Whenever you do so, could you please make sure you specify a descriptive interface reference to the personal-files interface so users can be aware of the accesses granted? Something like dot-config-slack, for example. Thanks!
Can other @reviewers please vote?
