Vlan from another AP to Mikrotik Hotspot

Hi.
My customer has an existing Ubiquity Unifi AP (that Needs to be reprogrammed because they wiped out the computer that had the controller on it),
anyway, I am installing a Mikrotik Routerboard AP for them, and what was mentioned somewhere else in this forum, is that I can keep the Unifi (in another part of the building), and configure it to basically be a dumb AP, that then forwards to the Routerboard AP.

The whole building is already wired with a standard network (using consumer grade Netgear ADSL Routers, etc, so nothing else that understands VLAN Tagging)

If I understand right :
Basically it will involve resetting the Unifi, then configuring it with the company SSID, no WPA key, and then setting it to bridge the LAN and Wireless ports (No Routing, No DHCP, etc),
Then setting it up with it's own VLAN (to isolate it's traffic from the rest of the network).

I then have to have the Mikrotik listen to the specific ethernet port, with a specific VLAN tag, and then handle it with the Builtin hotspot (I will not be using usermanager for now, just Trial Hotspot, and Users on the Hotspot page itself.

Basically
Wifi User --> Wireless (Ubiquity) Ethernet with VLAN 2 --> (Existing Network Switches) --> Ethernet 1 with VLAN 1 (Mikrotik)
Ethernet 1 with NO VLAN Tagging --> To Existing ADSL Router (Already Working)
Wireless for Admin Staff (Bridged with Ethernet 1, No Tagging (Already Working)
Wireless Hotspot for Customers (Already Working)Attached is my config where i figured out how to Bridged Ethernet1 and Wireless for Admin together (with no DHCP, the ADSL Router handles that.
I also Bridged Ethernet 4 with the Wifi Hotspot Interface, so that if a computer is plugged into Ethernet 4, it also goes through the hotspot.
The Bridge for the Hotspots is then assigned a DHCP address by the Mikrotik, and also masquerades to the existing adsl router.

So my main problems are

Figuring out how to configure the Ubiquity to be dumb, and also send traffic on the alternate VLAN to the Mikrotik
Figure out how to take the existing Ethernet1 of the Mikrotik, and split off a part of it, to be sort of a Seperate Interface that is only listening to the alternative VLAN.
Then I presume I can just bridge that subinterface with my Hotspot bridge, and it should work.

Any ideas or suggestions on how to do this.
The last time I used Mikrotik gear was about 12 years ago, when I worked for a local WISP.

Thanks
