hey guys! I'm creating a quizzes video in After Effects and aiming for maximum automation. II don't know much about expressions , and that's why I'm looking for some help here.

I have a JSON file containing answer names and the layer name of a "correct" emoji that I want to make visible over the correct answer. However, I need this "correct" emoji to stay visible after its initial appearance, showing the answers that have already been revealed until the end.

Is there an expression I can apply for this instead of do it manually ?

Here's an example of the current content in my JSON file:
"Comp": 1,
"answer": "She-Hulk",
"emoji": 10
"Comp": 2,
answer": "Iron Man",
"emoji": 3

(I guess that I need something like "if the emoji number in json file is equal to emoji layer number , then opacity =100. And if emoji number is equal to emoji layer number in a comp <=thislayer.name, then opacity 100) but I'm not sure, and chat gpt didn't help me too.
