<@247824634320257025> is right ☝️just to add a bit more, for the case where the set to filter is on the lower end of the spectrum, we are also working on a `BulkCheck` API that would allow you to send a list of `CheckPermission` requests. This opens the opportunity to all sort of optimizations plus sparing you the overhead of sending N `CheckPermission` calls.
