Row Level Security

I have a Data Table as shown below :-

I have two other tables, one for Territory ID mapping and the other for SKU ID mapping.
As shown below :-
Territory Table :-

SKU Table :-

The Territory and SKU tables are linked to Data Table with a Many to Many Relationship
I want to apply Row Level Security such that the rows in the Data Table are filtered
according to the user logged in and they should be able to view only the Territory or SKU assigned to them.

So if user [email protected] logs in them the Output should be :-

[email protected] only exists in Territory Table hence only filter from that table

if user [email protected] logs in them the Output should be :-

[email protected] only exists in SKU Table hence only filter from that table

if user [email protected] logs in, then the Output should be :-

[email protected] exists in both Territory and SKU Table hence filter from both the tables.

How should I go about creating Row Level Secutrity on these two independent tables?
