multiple SSID with vlan on RBK853

Hello,

I just unpacked my new Orbi (RBK853) system, set it up using the Orbi app.
I used the web interface to switch to AP mode because I would like to do a number of things:

1. Create multiple SSIDs (Lan, Guest, IOT)
2. Assign different VLANs to these SSIDs

Switching to AP worked just fine, But: I cannot even find how to do 1)  in the web interface. Does this mean it is not possible? How about assigning vlans?

Any help would be appreciated because if this functionality is not available I am sending this router back for a refund.
