Stable-Boy Plugin does not appear in top menu

[Sven]

After installing stable boy, stable-diffusion-webui and adding the directory from stable boy the plugin folder into the plugin preference list, stable boy does not appear in the top menu. stable-diffusion-webui does start in my browser and runs.
gimp 3.04. OSX 15.5. stable boy, stable-diffusion-webui from the current github versions. All installed to instructions of their website OK.

Anyone who installed stable boy? or Ideas?

Thanx in advance
Sven
