A program to create a local icon library for macOS?

Question

macOS

Gentlemen, tell me a program for creating your own collection of icons for poppy. I came across something like that, it was not cheap and there was no need. Now, as an economic designer, a mountain of files has accumulated - there is a need to streamline.
What is the meaning of software? An icon library is created from png/ai/svg folders, segmented by headings/topics. The program interface shows previews and allows you to drag and drop the desired one into any graphics editor or simply copy it to the clipboard.
