I need help for get_chat_string

[realalyssia]

Hello, I am capturing the following text in the chat, and I need to send the /sk accept (id) command. However, I don't know how to extract the id value from the function below. The player names in the screenshot I provided are constantly changing, and I need to focus on the "(34):" part.

I'm using this:

0B75: samp get_chat_string 98 text_to 1@ prefix_to 2@ color_to 3@ prefix_color_to 4@
