Using Script Canvas to convert seconds into minutes and seconds on clock

I’ve added an in game clock using the Script an In Game Timer with Amazon Lumberyard
video Script an In-Game Timer with Amazon Lumberyard | Lumberyard Tutorial 2020.10 - YouTube . The clock displays in seconds but I need to convert it into minutes and seconds. For example 5 minutes are displayed as 300 seconds but I need to show it as 5:00 and countdown from there.

Does anyone have an example of this using Script Canvas?

Thanks.
