Increase the size of the image in the expanded QComboBox list

Question

there is a small piece of program code. As it has a Combobox that contains a drop-down list. Please help with 2 questions:

1. how not to display the first picture in the expanded list? that is, you need the first picture to be visible when the list is not disclosed.
2. how do I increase the size of 2 and 3 images (which are in the drop-down list), for example, by 2 times?

Pictures are not attached, you can attach any other __

I read the documentation and did not find the answer, I asked a chatGPT question, but he also did not give the correct code

I need this as in the picture:
