Regular Expression to extract a 'word' from string. Need help.

Okay, I have figured it out! Took a wild guess and it worked. The code below gave me what I was after.

let msgBody = "Your AMG - Facility forms access code is 22RP3DPM. You will receive a link to your forms using your primary email address. You will need this access code to use the forms link. Further instructions will be available after using the access code to access the forms.";
let secCode = msgBody.match(/[0-9A-Z]{8}/); // the '/' before and after [0-9A-Z]{8} specifies it as Regular Expression

Log.Message("Security code is: " + secCode);

Log reads as: "Security code is: 22RP3DPM"

Hope this comes handy for someone else in my situation. :)
