New-MgPlannerTask: recurrence parameter

my company needs to create a few hundreds tasks in planner for a client
they asked me to automate the procedure, and i've been delving in this rabbit hole for a month

i started trying the cmdlet New-MgPlannerTask, but there are a few issues with that, so i looked at what was the request and proceded to test it manually in graph explorer

now, the current issue is: how do i add "recurrence" to the task parameters?

when i do, i get the following error:

Validation for field 'Recurrence.Schedule.Range', on entity 'Task' has failed:

and it's not really documented how to set this object
