Time off in MS Planner

Hi everyone.

I'm searching for a way to set my team's days off so that the timeline adapt the scheduled times.

In two attached images I'm trying to figure out how to customize resources calendar or a new work calendar template model.

I read about this functionality for the old project for the web but found no way to implement it to planner:

Any suggestions?

Thank you
