[Question] User permissions management using the sortable tree

[IDrissAitHafid]

Hello!
I have a use case for this tree, and I'm wondering if anyone has already done it or can suggest a solution that can help.

So, my problem is that I have used react-sortable-tree to represent an organization department's hierarchy. And now I want to add user permissions to it where not everyone can see all nodes.

Example:

I have just used this photo for simplicity.
So, for example, I have a user who's responsible for Level 2, so he has the right to see the subtree that includes Level 1 and Level 2 but he can write just to the nodes bellow Level 2. then the new tree becomes :

My stack is: React, Node and Mongo if you want to help out on any side ^^

Thank you in advance.
