Get group members count using facebook api

Question

Actually I can get a members list from an OPEN group on facebook using GET /v2.4/{group-id} HTTP/1.1. The problem is, that query return me not all the users on the group.

I.E, the group have 2020 members and graph api only returns me a list of size 1980. What happens with those 40 members?

There is a way I can get the exactly amount of members?, I been digging on the facebook API but I can't figure this out.

无法获得确切数量，某些用户可能已停用App平台。您永远无法确保能够访问所有人，没有可靠的方法来获得正确的小组成员数量。
