Too many screenshots so see this combined image: https://i.imgur.com/Jxn94XW.jpg
Scale a single pixel down and you risk losing the pixel. It would have been better if you posted the original rather than screenshots. A bit of pixel measuring and I think the first screenshot is x4. (1) No matter, I extracted that to an image without the background, which gave an image about 450x400 pix.
What sort of size in pixels are you hoping to end up with? You might get result by converting to a vector image. (2) A vector can scale up and down, best used for logos but works to a certain extent with your graphic. If you have lots of these to process, install Inkscape, for the occasional bitmap -> svg there are free online converters.
Importing the svg into Gimp and it initially shows the original size (3) but change that to scale up or down, I think that anything less than 40 pix (4) might be a step too far.
That gets a small image in Gimp with some detail and in this case some of the pixels are semi-transparent (5) Improve that using Layer -> Transparency -> Semi-Flatten setting black as the colour. (6)
Attached the svg (unzip it) for you to play with, but please do experiment.
