We ran into the same issue - I'm wondering if you have a solve for this?

I have the same question as well. This is quickly becoming a blocker for us to user Looker in our embedded product. Need a solution for this as soon as possible.

Following up on this as this thread was from 3 months ago, I’m wondering if Looker added dynamic tiles on looker dashboards based on user attributes? Unfortunately i can’t access the portal link shared above so I can’t upvote.
