How to Implement User-Specific Default Slicer Values and Save Functionality in Power BI ?

Hi all,

I'm working on a Power BI report embedded in a web application, where I want to implement the following functionality:

1. When a user logs in for the first time, they should see the report with a default view (based on their region or other criteria from a security table).
2. The user can select other regions/products using slicers, and they should be able to save this customized view.
3. When they log in again, the saved slicer selections should appear as their new default slicer selections.

Any code examples, best practices, or advice would be greatly appreciated!

Thank you!
