Description: It is necessary to create a JavaScript script for the Tampermonkey extension. The script will work in an internal CRM system.Logic of operation: The script must read the unique text ID of the current active dialogue on the page (there are a total of 5–10 different IDs). Depending on the ID, the script takes the corresponding text instruction (System Prompt) from the settings. The mapping of parameters by ID should be moved to a separate convenient settings window for the script. When a new message appears in the chat window, the script sends this text along with the prompt via the OpenAI API (model gpt-4o-mini). The received response is inserted into the text input field and initiates sending with a random delay of 20–45 seconds to simulate the natural operation of the operator.Work is purely with text. Budget — 6000 UAH. I am waiting for proposals from developers with experience in working with the OpenAI API and writing browser automation scripts.
