Manim Diagonal bar_names - bar-chart

Question

I want to animate a bar chart in manim and it works just fine. However, the bar_names are long and have to be displayed rather small. Is there a way to rotate them so they can be displayed bigger?
CONFIG = {
"max_value" : 100,
"bar_names" : ["Fleisch von Wiederkäuern","Anderes Fleisch, Fisch","Milchprodukte","Früchte", "Snacks, etc.","Gemüse","Pflanzliche Öle","Getreideprodukte", "Pflanzliche Proteine"],
"bar_label_scale_val" : 0.2,
"bar_stroke_width" : 0,
"width" : 10,
"height" : 6,
"label_y_axis" : False,
}
def construct(self):
composition = [96.350861, 18.5706488, 14.7071608, 8.25588773, 7.33856028, 4.24083463, 1.65574964, 1.36437485, 1]
chart = BarChart(values=composition, **self.CONFIG)
self.play(Write(chart), run_time=2)```

Maybe something like this?
(I just made new labels so delete the old ones, or delete their size)
(also I modified some of the names because my Latex crashed with some characters)
CONFIG = {
"height": 4,
"width": 10,
"n_ticks": 4,
"tick_width": 0.2,
"label_y_axis": False,
"y_axis_label_height": 0.25,
"max_value": 100,
"bar_colors": [BLUE, YELLOW],
"bar_fill_opacity": 0.8,
"bar_stroke_width": 0,
"bar_names": ["Fleisch von Wiederkuern","Anderes Fleisch, Fisch","Milchprodukte","Frchte", "Snacks, etc.","Gemse","Pflanzliche le","Getreideprodukte", "Pflanzliche Proteine"],
"bar_label_scale_val": 0
}
def construct(self):
bar_names=["Fleisch von Wiederkuern","Anderes Fleisch, Fisch","Milchprodukte","Frchte", "Snacks, etc.","Gemse","Pflanzliche le","Getreideprodukte", "Pflanzliche Proteine"]
Lsize=0.55
Lseparation=1.1
Lpositionx=-5.4
Lpositiony=2
bar_labels = VGroup()
for i in range(len(bar_names)):
label = TexMobject(bar_names[i])
label.scale(Lsize)
label.move_to(DOWN*Lpositiony+(i*Lseparation+Lpositionx)*RIGHT)
label.rotate(np.pi*(1.5/6))
bar_labels.add(label)
composition = [96.350861, 18.5706488, 14.7071608, 8.25588773, 7.33856028, 4.24083463, 1.65574964, 1.36437485, 1]
chart = BarChart(values=composition, **self.CONFIG)
chart.shift(UP)
self.play(Write(chart),Write(bar_labels), run_time=2)
