Tensorflow does not detect GPU altough the GPU driver and Cuda are installed

I have an Nvidia GPU (Geforce RTX 3090) and the driver is displayed in Nvidia Control Panel. I also have installed the latest version of Cuda. However, when using the following code in Python with TensorFlow:

gpus = tf.config.list_physical_devices('GPU')
if not gpus:
    print("No GPUs detected")
else:
    print("GPUs detected:")
    for gpu in gpus:
        print(gpu)

It always shows me, that no GPU is detected. Can you tell me what I have to do in order to make Tensorflow use the GPU?

Reminder: Does anyone have any suggestion as to what I can do in order to make Tensorflow detect and use the GPU? I'll highly appreciate every comment.
