How to open and edit the shader I created?

[Jo Jonathan]

Hello. I just bought the asset. I'd like to ask a question. How do I open my own shader?
For example. I created a shader in the shadero editor window but I didn't press Save Shader Project button.
Later , I tried to edit the shader I created but I failed to find a button or any way to load my own shader, the ONLY way I could load a shader is through load shader project button.
Is there a way to open and edit the shader I just created?
