Почему в коде питон не работает кнопка?

вот код, кнопка не хочет создаваться (код не полный)

RESTART_BUTTON_WIDTH = 100
RESTART_BUTTON_HEIGHT = 50
RESTART_BUTTON_X = 0
RESTART_BUTTON_Y = 0
RESTART_BUTTON_COLOR = (255, 0, 0) # Red color

def draw_restart_button(screen):
pg.draw.rect(screen, RESTART_BUTTON_COLOR,
(RESTART_BUTTON_X, RESTART_BUTTON_Y, RESTART_BUTTON_WIDTH,
RESTART_BUTTON_HEIGHT))

def handle_restart_button_click(pos):
if RESTART_BUTTON_X <= pos[0] <= RESTART_BUTTON_X + RESTART_BUTTON_WIDTH and \
RESTART_BUTTON_Y <= pos[1] <= RESTART_BUTTON_Y + RESTART_BUTTON_HEIGHT:
main()
running = True
while running:
for event in pg.event.get():
if event.type == pg.QUIT:
running = False
elif event.type == pg.MOUSEBUTTONDOWN:
handle_restart_button_click(event.pos)
