Creating, getting and deleting Shifts using PowerShell

Hi,

I am trying to prototype an interface for my organisation which can list, create and delete Shifts using PowerShell. The interface would take in data from a seperate application I cannot control, so I am restricted to using PowerShell.

Is it only possible to do this by using appropriate MS Graph API calls and managing the associated permission scopes? Ideally if there was a way to do it directly through PowerShell this would be preferred.

Any guidance or alternate methods on how I could go about designing this interface would be appreciated.
