RLS different filters - same rol

Good morning,

I have created a dashboard with 2 pages for a sales contest and I need to create roles for different leagues:

- Page 1: Contains the ranking of all competitors. It must be visible to all participants
- Page 2: Contains the sales data behind the ranking. It should be visible only to the owner of the sales.

Would it be possible to create each role that combines both filters? or
is it necessary to create a role for each filter, if possible, and how would both roles be combined?
