I am trying to create a planner board using graph api.

I am able to get the basic board. But instead I want to create a planner using lets say "Software Development" Template.

Or Option 2 would be to create a planner board than how to add a timeline using graph API itself

I have tried various codes given by chat gpt and also my basic ones.

POST .0/planner/plans Content-Type: application/json

{ "owner": "gid", "title": "SD", "template": "Software Development" }

The basic one with owner and title works and in this too it makes it but just without template.

Also tried "preferredtemplate" but that didn't work either.
