what are the implications of fls filters on aggregation?

i’m still in the process of deciding whether to use search-guard so i’m sorry if this is too general a question.

say if i set up a fls filter for user with role ‘marketing’ that’s filtering out the field ‘client.email’, would the ‘marketing’ role still be able to do a ‘term aggregation’ against ‘client.email’?

my understanding is that all returned documents wouldn’t have the field ‘client.email’ anymore, which is great, but what about inside the response for aggregation?
