Inter-Process GPU Texture Sharing

With 4.26 there is a new plugin “Texture Share” and after enable it there is an option in textures named “Share”, but how can I use this “shared” texture on other unreal project.

I know that I must be running the application where I marked “Share” in the texture, but where I can find a shared texture in my other project?

kindly provide c++ only solution as i am also looking for the same ITextureShare…
