Check group membership

getUsersInGroup() filters a candidate list to the user IDs that belong to one group. It returns string[] or null.

import { getUsersInGroup } from '@/uni_modules/unix-openim-sdk'

const members = await getUsersInGroup({ groupID, userIDList: candidateUserIDs })

The result contains user IDs only, not member profiles. Query specified members when the UI needs in-group nickname, role, or mute state. Deduplicate input first and interpret results by value rather than input position.

Treat null as no valid result and an empty array as no matching members. This operation does not add, invite, or remove members and does not trigger a member event.
