How to disable prejoin page on iOS Mobile sdk?

Hi,
How do we disable the prejoin page on iOS Mobile SDK ?
I am trying to set below code in JitsiMeetConferenceOptions, but it is not working.
[builder setConfigOverride:@“prejoinPageEnabled” withBoolean:NO];
[builder setConfigOverride:@“requireDisplayName” withBoolean:false];

Here is the code :->

JitsiMeetConferenceOptions *options = [JitsiMeetConferenceOptions fromBuilder:^(JitsiMeetConferenceOptionsBuilder *builder) {
builder.serverURL = [NSURL URLWithString:@“https://vc.mindemr.com/361”];
builder.room = self.selectedJitsiObj.p_user_roomName;
builder.audioOnly = NO;
builder.audioMuted = NO;
builder.videoMuted = NO;
JitsiMeetUserInfo *info = [[JitsiMeetUserInfo alloc] initWithDisplayName:self.selectedJitsiObj.p_user_displayName andEmail:@“” andAvatar:nil];
[builder setUserInfo:info];
[builder setFeatureFlag:@“raise-hand.enabled” withBoolean:NO];
[builder setFeatureFlag:@“invite.enabled” withBoolean:NO];
[builder setFeatureFlag:@“toolbox.enabled” withBoolean:YES];
[builder setFeatureFlag:@“filmstrip.enabled” withBoolean:NO];
[builder setFeatureFlag:@“welcomepage.enabled” withBoolean:NO];
[builder setConfigOverride:@“requireDisplayName” withBoolean:NO];
[builder setConfigOverride:@“prejoinPageEnabled” withBoolean:NO];
}];
