Apply RLS to New Page Navigator?

Hi, Anonymous 

Sorry, according to my test, this new feature is not very helpful to RLS. You still need to switch to different pages through the cooperation of slicer and button as before.

Reference:

Did you know you can now selectively show report pages for specific users in Power BI? - Reporting/Analytics Made easy with FourMoo and Power BI

Create page and button navigators - Power BI | Microsoft Docs

Did I answer your question ? Please mark my reply as solution. Thank you very much.
If not, please feel free to ask me.
