Thanks! I need a little help understanding how to use the new interface. For example, I have this JavaScript script where I'm currently storing the accountId and password in plaintext right in the script. How would I modify it to now use the new interface?
(async () => {
class Logger {
constructor() {
this.logLevels = {
INFO: "INFO",
ERROR: "ERROR",
};
}
log(message, level = this.logLevels.INFO) {
const now = new Date();
const formattedDate = now.toLocaleDateString("en-GB"); // European format
const formattedTime = now.toLocaleTimeString();
const timestampStyle = "color: cyan;"; // Cyan
const levelStyle =
level === this.logLevels.ERROR ? "color: red;" : "color: green;"; // Red for ERROR, Green for INFO
console.log(
`%c${formattedDate} ${formattedTime} - %c${level} - %c${message}`,
timestampStyle,
levelStyle,
"color: white;"
);
}
}
const logger = new Logger();
const BASE_URL = "https://share2.dexcom.com";
try {
const loginHeaders = {
"Content-Type": "application/json",

// How to use the new interface here?
const loginPayload = JSON.stringify({
accountId: "redacted",
