Unity needs to load the sprite from an arbitrary folder (not from Resources). How to do it?

Question

Unity

I am developing a map editor. We need to add the ability to create blocks directly from the program, and not through Unity itself. However, for this I need a folder in which the sprites will be stored, or rather, how can I download these sprites from there, if the user can add them there (to this folder)?
Using Resources.Load is not appropriate.
The code structure is as follows:
gameObject.GetComponent().sprite = sprite to get from an arbitrary folder.

Folder StreamingAssets https://docs.unity3d.com/Manual/StreamingAssets.html
Put everything in it, after the build it will be like a separate folder where the player can make changes
