The problem at the end can be solved using a closure, here's the code that i wrote for it:

(resolve, reject) => {
// closure function
function main_button_click_handler (event) {
event.preventDefault();
resolve(main_button_click_event_listener, main_button_click_handler);
}
main_button_click_event_listener = main_button.addEventListener("click", main_button_click_handler);
}
);
main_button_click_promise.then(
(main_button_click_event_listener, main_button_click_handler) => {
document.removeEventListener(main_button_click_event_listener, main_button_click_handler);
console.log("Promise resolved");
}
)
console.log("End of script");
