Secondary G4 Time Zone and Monster Insights

Hi, I live in Australia and have alert in Journey dashboard to create a secondary G4 property for the Eastern time zone. I'm not sure where Monster Insights is inserting code to add the secondary property and really don't want to break my tracking for my existing property. How have others dealt with this. I currently don't have Site Kit app. Can this automate creating two tracking scripts for me instead? I'm not sure if this will be compatible with what Monster Insights has already created. I'm using Avada Theme and can't see where Monster Insights has inserted script into my header code from my wordpress dashboard. I just know this was all working ok for me before the request for secondary G4 property to be added to site. Thanks for any help/insights you can provide. Site is https://www.thecrochetfix.com.
