Star data modelisation for multiple child-parent level table [closed]

I’m beginner to data-modelisation.
I’m trying to follow a star model approach, but I’m blocked with a part of my data model

The original model is the following

A company has 0 or multiples regions
A region has 0 or multiples departments
A departement has 0 or multiple sites
Multiple departments can be grouped inside a “branch” (not mandatory)

And my main table (fact table), “Records” are linked to 1 mandatory site.

I was doing a dimension table with that :

• SiteId
• SiteLabel
• BranchId?
• BranchLabel?
• DepartmentId
• DepartmentLabel
• RegionId
• RegionLabel
• CompanyId

CompanyLabel

But I’m not sure, shouldn’t I divide this table in multiple tables ?

My uses cases are to sometimes filter by branch, sometimes by site, sometimes multiples regions accross multiple companies etc in PowerBI

Thank you
