What is the best way to make this script/macro/bot?

Question

Programming

Hello.
I came up with the idea to make a bot / macro / script for catching fish in Gta V. Its essence is that it casts a fishing rod itself (on the E key), after which, after some time, pictures with letters appear from the bottom center of the screen. The pictures change , that is, there was a picture with the letter G, it became with the letter J. The bot / macro must read the picture and press / press the key.
If there was a picture with the letter J, then he should press the J key. There are 4 keys in total (F, G, J, K). The difficulty is that I have only a superficial idea of ​​\u200b\u200bthis bot / script. where this is implemented. Thanks in advance. They didn’t ban me on Google, I tried to find it, nothing happened. Suddenly someone had experience. If someone decides to write this, there will be a moderate reward.
