There are still three osgraph icons here.

FYI, there is another way to use local assets directly to avoid the introduce of base64 images :) Maybe have a try

If we can directly pack the image into the extension and use them in local env, that should be better than base64 encoding. Because usually base64 encoding will be a little bit larger than image format.

I will follow this approach and directly pack the images into the extension. This will ensure better performance and avoid the overhead of using base64 encoding.

Finally, it is necessary to align the style with the original GitHub style. At present, when on the same line, it will be slightly higher than the original label.

Yes, this is the revised picture.
