Converting seconds to show minutes and seconds

Hi there, I'm new to yaml files so apologies if I have missed something obvious.

I've set up a wallboard that shows the number of waiting contacts in several queues plus the longest waiting contact in those same queues but it displays the time in seconds so a call waiting 3 minutes is seen as 180.

Is there a way to convert the display to show it as 3m 0s or 3.00?

Kind Regards
Tony

The issue names YAML configuration but no file, test, or entry point. Start by locating the wallboard code that formats the longest-waiting-contact value and the related YAML settings. Done means the display presents waiting times in minutes and seconds, or in the requested decimal-minute format, and the wallboard output is verified.
