How to restrict adding more members in the group using StreamChatSwiftUI

Question

i am using StreamChatSwiftUI builit in ChatChannelView for chat, i see there is an option to 'add members' in the group info. 1 - How can i disable or hide this option ? 2 - There is no remove member option, how can i show remove existing member?

i tried

.navigationDestination(isPresented: $vm.isChannelCreated) {
            if let controller = vm.channelController{
                ChatChannelView(
                    viewFactory: CustomUIFactory.shared,
                    channelController: controller
                )
            }
        }
