Access Session Variables

we have encountered a challenge. We're searching for a way to access session variables within a Metabase query itself.

Specifically, we have a query that returns data for multiple users. Our goal is to restrict each user's access to only their own data, without creating separate queries for each individual. If there were a way to access a user's email address through their login details within the query, we could use that information to filter the data accordingly.

This has been asked many, many times before.
To do any sort of row level security, you need to pay for the full version or embed the dashboard with a hidden filter.
