How can I create a Dax-based RLS in power BI service?

I'm working on a report in Power Bi service & would like to create a dynamic RLS based on user principle ID like the desktop app. But in the Manage Security Roles datamart, I could not find any way to switch to DAX editor.

I have multiple managers, and want to make a dynamic RLS for each of them, so manually making roles for each team is not a good approach here. Can anyone help me to check if there are any other way?
