I have successfully created a sub menu extending on the shift + A menu in the shader editor, but I would like to have the options show up as results in the search bar. Is this even possible, and if so how can it be done?

I have successfully created a sub menu which extends the Shift+A menu in the shader editor but I would like to have the options show up as results in the search bar. Is this even possible, and if so how can it be done?
