When you make pull requests are commenting on a case sometimes its easier to have a gif animation of your issue or the problem you solved rather than describing in million words. You can do that pretty easily on a mac using couple of commands. Use quicktime player to do a screen recording.
Once the screen recording is done the run below command with input parameter to create a gif.
Prequisite is to have ffmpeg installed which, you can do that from brew install ffmpeg.
ffmpeg -i [input_file] -filter_complex 'fps=10,scale=[width]:-1:flags=lanczos,split [o1] [o2];[o1] palettegen [p]; [o2] fifo [o3];[o3] [p] paletteuse' [output_file].gif
Don’t forget to fill in the parameter in square brackets.
