Changing ACL setting only possible by a member of Sendbird’s Solutions Engineering team. Please can you direct message me with your application id and I will ask internally if we can support you in changing these settings.
Generally, are we able to deactivate any SDK function we want using these ACL settings?
We do have ACLs that allow us to prevent some features from being utilized by the SDK. The User List is one of those options. The list is not exhaustive and thus you cannot deactivate any SDK function you want.
Checking if a user is online would fall under the User List ACL. There is no granularity there.
Invite users as members is included as part of Group Channel Invite ACL.
