For the second use case:, it's how to display the action buttons on a list of data (to disable the action buttons for which the user has no access). Yes, sorry for the noob questions 😦 Let's say I display 100 items per page (and let's say my app can show 4 actions per line). The naive way would be to call the CheckPermission API for each button and per-line. Hence 400 calls to the CheckPermission API. Other than that, I could rely on the previous solution (permission locally stored on my app database with lookup watch and tiger cache) Is there another way ?
