TOS5 2 VLANs over lan0 to a Switch

I’d like to have one or more guest ethernet ports on a switch that is currently connected to lan0 of my Turris Omnia (running current Turris OS 5).
The connected switch is capable of VLANs (TP-Link Smart Switch).

What configuration do I have to do on my Turris to enable VLAN1 (home vlan) and VLAN2 (guest vlan)?

Is it possible to put VLAN1 into “br-lan” and VLAN2 into “br-guest_turris”?
