For our mac users who have been asking this for a while now via user voice, you can now copy and paste images on flows and 1-1s from your clipboard directly without having to drag drag/ attach images.
What this means apart from more power to 'Ctrl+Command+Shift+4' on macOS High Sierra, is more time saved for you and ease of use!
We hope you enjoy this value add!
