I had this error for permissions quicksight:SearchUsers and quicksight:SearchGroups
My AWS admin was able to add the SearchGroups permissions but did not see the SearchUsers permission listed. I also confirmed this on a personal account.
Here is the search results in IAM when trying to assign a policy:
I then tried to manually edit the permission incase it just wasn’t listed through the self-help tool but that did not work either:
Is this permission by chance under some other name?
If you search for the quicksight:SearchUsers permission, it doesn’t come up. The policy editor also throws a red X when manually adding it to the policy but if you ignore the error and push it through, it does seem to have worked.
As a side note, I also needed to add, quicksight:SearchDataSets and quicksight:SearchDataSources to the policy for managing assets.
