I’m trying to code a Python Fu plugin for GIMP, but it doesn’t appear in my menus. Is there a mistake in my code ? How can I fix this ? Thank you a lot for reading me !

#!/usr/bin/env python

from gimpfu import *
import random as rd

def encode(image, drawable):
    newDrawable = drawable
    width = pdb.gimp_image_width(image)
    height = pdb.gimp_image_height(image)
    initialLayer = pdb.gimp_image_get_active_layer(image)
    title1 = ""
    title2 = ""
    for k in range(10):
        title1 += str(rd.randint(0,10))
        title2 += str(rd.randint(0,10))
    layer1 = pdb.gimp_layer_new(image, width, height, 0, "title1", 100, 0)
    layer2 = pdb.gimp_layer_new(image, width, height, 0, "title2", 100, 0)
    image.add_layer(layer1)
    image.add_layer(layer2)
    # Passe en revue l'intégralité des pixels
    for x in range (width):
        for y in range(height):
            #Lecture
            pdb.gimp_image_set_active_layer(image, initialLayer)
            newDrawable = image.layers[2]
            pixel = pdb.gimp_drawable_get_pixel(newDrawable, x, y)[1]
            #Mélange aléatoire des valeurs RVB
            newPixel1 = (rd.randint(0,pixel[0]+1), rd.randint(1,pixel[1]+1), rd.randint(2,pixel[2]+1))
            newPixel2 = (pixel[0] - newPixel1[0], pixel[1]- newPixel1[1], pixel[2]- newPixel1[2])
            #Écriture
            pdb.gimp_image_set_active_layer(image, layer1)
            newDrawable = image.layers[1]
            pdb.gimp_drawable_set_pixel(newDrawable, x, y, 3, newPixel1)
            pdb.gimp_drawable_update(newDrawable, 0, 0, width, height)
            pdb.gimp_image_set_active_layer(image, layer2)
            newDrawable = image.layers[0]
            pdb.gimp_drawable_set_pixel(newDrawable, x, y, 3, newPixel2)
            pdb.gimp_drawable_update(newDrawable, 0, 0, width, height)


register(
    "python_fu_encode",
    "Encodes an image into two ones.",
    "Creates two layers. For each pixel, a random amount of intensity will be removed and added to one of the layers ; the other layer gets the rest.",
    "Scapin", "Scapin", "2024",
    "Encode",
    "<Image>/Filters/Encode"
    "RGB"
    [
        (PF_IMAGE, "image", "Takes current image", None),
        (PF_DRAWABLE, "drawable", "Input layer", None)
    ],
    [],
    encode)

main()

I tried ;

-changing the plugin file pathes
-reinstalling/updating GIMP
-changing the structure of the register function
